NIFI-12969: Fixed a typo in the #isTempDestinationNecessary method, where we were comparing existingConnection.getProcessGroup() to newDestination.getProcessGroup(), instead of comparing existingConnection.getDestination().getProcessGroup() to newDestination.getProcessGroup(). I.e., we were comparing the Destination's PG to the Connection's PG instead of comparing Destination's PG to Destination's PG. This resulted in using a temporary funnel when we shouldn't. And as a result it attempted to change a Connection's Destination while the destination was running. 

This closes #8600.
