Fix part name when changing instrument
Fix #22235 : some ledger lines are too wide in chords with seconds.

If a chord contains an interval of a second (i.e. with flipped note heads) but the flipped note head(s) require no ledger lines, lines wide as the entire chords are generated.

Fixed by constructing ledger lines in two passes each from the 'outside' of the chord toward the staff, once for lines below and once for lines above the staff

See http://musescore.org/en/node/22235 for details and a sample. The commit should fix both issues in the post

NOTE: I had to remove the 'experimental' feature to avoid collision between ledger lines and accidentals: the relevant test is there, but what to do in this case is much more complex than before.
