This defer seems problematic for unlocking. What happens when a second entry in this for loop has an error?

This PR aligns the behavior of receipt modacks with the Python client. Specifically, if exactly once delivery is enabled, receipt modacks that fail should be retried up to 3 times (similar to lease modacks), but message processing should be blocked on the result of this modack.
This PR also removes a test with the fake since
DeadlineExceedederrors will never happen in theNackcase if modacks are never successful.Fixes #7585
