fix bug in lifetime of MidiView::_ghost_note

Browse source 
As noted in 8b389ee829, we now clear the _note_group container
before any other Note items might be deleted. But since this
may delete the _ghost_note, we have to be sure to reset
that to a null ptr to avoid a double-free later during
~MidiView
