Fix #7007: ::clear_owned_changes() on rippled Playlist before commit

Browse source 
RegionMoveDrag::finished_no_copy() calls ::clear_changes() on every selected
Region and then sets their positions again before committing the command to the
UndoHistory. By doing that no changes from the previous transaction spill over
into the current transaction.

This needs to be done in a similar way by in RegionRippleDrag::finished()
because otherwise a following undo action would also undo the changes of the
previous transaction for all the non selected rippled regions.

RegionRippleDrags across tracks are still borked, though.
