When deserializing a DynamodbEvent, the contained DynamodbEvent.DynamodbStreamRecord#dynamodb (type: StreamRecord) is completely loaded: keys and new and old images (when present, obviously).

But when attempted to deserialize directly a DynamodbEvent.DynamodbStreamRecord, the contained DynamodbEvent.DynamodbStreamRecord#dynamodb (type: StreamRecord) is NOT loaded correctly.

Created demonstration test available at Add test for DynamodbEvent.DynamodbStreamRecord load:

• Added EventLoaderTest#testLoadDynamodbStreamRecord() fails.

Why? What am I missing?
