### Current Behavior

I created an SQS FIFO queue with content based deduplication and sent a message that contains the same messageBody and attributes twice.

The message gets sent and received by the queue twice.

Im using the latest version of localstack with docker-compose.


### Expected Behavior

When ContetBasedDeduplication is set to true a message with the same body should only be recieved once by the queue during the 5 minute deduplication interval.

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

create queue
```
sqs_client.create_queue(
            QueueName='my_queue.fifo',
            Attributes={
                'FifoQueue': 'true',
                'ContentBasedDeduplication': 'true'
            },
        )
```

send message
```
item = {'hello': 'hola'}
sqs_client.send_message(
            QueueUrl='my_queue.fifo',
            MessageBody=json.dumps(item),
            MessageAttributes= {'hello': {'StringValue': 'hola', 'DataType': 'String'}},
            MessageGroupId='group-1'
        )
```





### Environment
