  Log Message:
  -----------
  Fix keeping unacknowledged messages in queue

1. If an async message results in zero UcfChangeType objects
(and no exception), it is now correctly acknowledged.

2. Also, added logging of exceptions that occur during async update
message transformation.

This resolves MID-7086.
