[PDI-12599] - MongoDB Output step has a race condition in batch insert retries that can cause errors to be logged.

It seems to be impossible to prevent a driver from throwing an exception, thus it makes sense to merely avoid it after recognising the case properly.
This if block has comments saying it will skip logging the error, but it still makes the call to logError exactly the same as the old code.  Was this line maybe supposed to be commented out?
