Wrong undo visibility change for dotted note, where note and dot have different visibiilities
Linux. Affects 2.0.3 and master.
1. my first score
2. "N" "." "C" "N"
3. Select dot and press "V"
4. Select note and press "V"
Expected: note should be visible, but dot invisible.
Result: Both note and dot are visible.
I think the issue is in Note::setProperty, where, for visibility, the note changes the dot's visibility too. During undo, the note still changes the dot's visibility, even when it isn't supposed to.
