### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

Here are the kinesis events from inserting/deleting a dynamodb item:

```
{"eventID":"cf1199b0","eventVersion":"1.1","dynamodb":{"ApproximateCreationDateTime":1.635284406858227E9,"SizeBytes":56,"Keys":{"hash":{"S":"hash-691"},"range":{"S":"range-153"}},"NewImage":{"hash":{"S":"hash-691"},"range":{"S":"range-153"}}},"awsRegion":"us-east-1","eventSource":"aws:dynamodb","eventName":"INSERT","tableName":"bug"}

{"eventID":"976b515b","eventVersion":"1.1","dynamodb":{"ApproximateCreationDateTime":1.6352844070969691E9,"SizeBytes":4,"Keys":{"hash":{"S":"hash-691"},"range":{"S":"range-153"}},"OldImage":null},"awsRegion":"us-east-1","eventSource":"aws:dynamodb","eventName":"REMOVE","tableName":"bug"}
```

Note that the remove event has `OldImage` = `null`

### Expected Behavior

I expected `OldImage` to be `{"hash":{"S":"hash-691"},"range":{"S":"range-153"}}`.

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

```
# Create table/stream and hook them up
docker-compose up -d

# Create/delete an item
./mvnw -P write-to-dynamodb

# See the produced records
./mvnw -P watch-kinesis
```

### Environment

```markdown
- OS: Manjaro Linux
- LocalStack: 0.12.19
```
