Increment delivery counter on XCLAIM unless RETRYCOUNT specified

Browse Source 
The XCLAIM docs state the XCLAIM increments the delivery counter for
messages. This PR makes the code match the documentation - which seems
like the desired behaviour - whilst still allowing RETRYCOUNT to be
specified manually.

My understanding of the way streamPropagateXCLAIM() works is that this
change will safely propagate to replicas since retry count is pulled
directly from the streamNACK struct.

Fixes #5194
