UX/Interaction bug (incorrect behaviour)

Bug description

The microtonal accidentals don't work correctly if used on a staff of a transposing instrument when switchin between concert pitch off to concert pitch on, or vice versa. By switching between the two modes, the playback remains correct, but the accidental remains unchanged, regardless of the accidental that should instead be used to achieve the transposed note.

Steps to reproduce

1. Create a score for a transposing instrument (in this example an F horn). Keep the concert pitch option off.
2. Write a note that will have an accidental when transposed to concert pitch (in this example a written F / sounding Bb).
3. Apply a microtonal accidental to that note (in this example a half sharp).
   
4. Turn the concert pitch option on. The note will be displayed as a B half sharp (instead of the correct B half flat), but the playback will play a B half flat regardless.
   

The same issuo also happens in reverse:

1. Create a score for a transposing instrument (in this example an F horn). Keep the concert pitch option on.
2. Write a note that will have an accidental when transposed to concert pitch (in this example a written B / sounding F#).
3. Apply a microtonal accidental to that note (in this example a half flat).
   
4. Turn the concert pitch option off. The note will be displayed as an F half flat (instead of the correct F half sharp), but the playback will play a (concert pitch) B half flat regardless.
