dynamodbstreams describe-stream shows stream not found but the stream is there in list-streams

Steps to recreate:
1. create dynamodb table, 
```
aws dynamodb create-table --table-name MusicCollection --attribute-definitions AttributeName=Artist,AttributeType=S AttributeName=SongTitle,AttributeType=S --key-schema AttributeName=Artist,KeyType=HASH AttributeName=SongTitle,KeyType=RANGE --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5 --endpoint http://localhost:4569
```

2. add stream
```
aws dynamodb update-table --table-name MusicCollection --stream-specification StreamEnabled=true,StreamViewType=NEW_IMAGE --endpoint http://localhost:4569
{
    "TableDescription": {
        "TableArn": "arn:aws:dynamodb:eu-central-1:000000000000:table/MusicCollection", 
        "AttributeDefinitions": [
            {
                "AttributeName": "Artist", 
                "AttributeType": "S"
            }, 
            {
                "AttributeName": "SongTitle", 
                "AttributeType": "S"
            }
        ], 
        "ProvisionedThroughput": {
            "NumberOfDecreasesToday": 0, 
            "WriteCapacityUnits": 5, 
            "LastIncreaseDateTime": 0.0, 
            "ReadCapacityUnits": 5, 
            "LastDecreaseDateTime": 0.0
        }, 
        "TableSizeBytes": 0, 
        "TableName": "MusicCollection", 
        "TableStatus": "ACTIVE", 
        "StreamSpecification": {
            "StreamViewType": "NEW_IMAGE", 
            "StreamEnabled": true
        }, 
        "LatestStreamLabel": "2019-09-21T10:47:14.246", 
        "KeySchema": [
            {
                "KeyType": "HASH", 
                "AttributeName": "Artist"
            }, 
            {
                "KeyType": "RANGE", 
                "AttributeName": "SongTitle"
            }
        ], 
        "ItemCount": 0, 
        "CreationDateTime": 1569062831.736, 
        "LatestStreamArn": "arn:aws:dynamodb:eu-central-1:000000000000:table/MusicCollection/stream/2019-09-21T10:47:14.246"
    }
}
```
3. Note LatestStreamARN from output ```"LatestStreamArn": "arn:aws:dynamodb:eu-central-1:000000000000:table/MusicCollection/stream/2019-09-21T10:47:14.246"```

4. List streams:
```
aws dynamodbstreams list-streams --endpoint http://localhost:4570                                                                                                                  
{
    "LastEvaluatedStreamArn": "TODO", 
    "Streams": [
        {
            "TableName": "MusicCollection", 
            "StreamArn": "arn:aws:dynamodb:eu-central-1:000000000000:table/MusicCollection/stream/2019-09-21T10:47:16", 
            "StreamLabel": "TODO"
        }
    ]
}
```
5. Compare StreamARN to step 3.

Expected behavior: they should match (AWS dynamodb/streams behavior)
region_name = extract_region_from_arn(queue_arn)
    queue_name = sqs_queue_name(queue_arn)
    client = connect_to_service('sqs', region_name=region_name)
    response = client.get_queue_url(QueueName=queue_name)
    return response['QueueUrl']
def sqs_receive_message(queue_arn):
    region_name = extract_region_from_arn(queue_arn)
    client = connect_to_service('sqs', region_name=region_name)
    queue_url = get_sqs_queue_url(queue_arn)
    response = client.receive_message(QueueUrl=queue_url)
    return response
def mock_aws_request_headers(service='dynamodb', region_name=None):
    ctype = APPLICATION_AMZ_JSON_1_0
    if service == 'kinesis':
        ctype = APPLICATION_AMZ_JSON_1_1
    elif service == 'sqs':
        ctype = APPLICATION_X_WWW_FORM_URLENCODED
    access_key = get_boto3_credentials().access_key
    region_name = region_name or config.DEFAULT_REGION
    headers = {
        'Content-Type': ctype,
        'Accept-Encoding': 'identity',
        'X-Amz-Date': '20160623T103251Z',
        'Authorization': ('AWS4-HMAC-SHA256 ' +
            'Credential=%s/20160623/%s/%s/aws4_request, ' +
            'SignedHeaders=content-type;host;x-amz-date;x-amz-target, Signature=1234') % (
                access_key, region_name, service)
    }
    return headers
