Real SQS throws `There should be at least one SendMessageBatchRequestEntry in the request. (Service: AmazonSQS; Status Code: 400; Error Code: AWS.SimpleQueueService.EmptyBatchRequest;` when there is a send batch of zero size.

This would be useful to mimic inside localstack in order to find these bugs earlier.
