Fix #6673 - another prematurely closed undo transaction.

Browse Source 
- add_midi_region used to commit, resulting in
	  _region->set_position() adding a command when there was
	  no current transaction. The sub-bug here was that repeatedly
	  calling set_position() on the new region resulted in nonsensical
	  automation movement after the drag.
