Grace notes alterations for trilled notes are ignored on the trill
Steps to reproduce:
1. Create a note.
2. Add a trill to the note. Start playback: the trill plays diatonically (as expected)
3. Add a grace note (of any kind: acciaccatura, appoggiatura, grace note) to the trilled note. Start playback: the trill plays diatonically (as expected)
4. Alter chromatically the grace note (e.g raise or lower by a half tone). Start playback: the trill still plays diatonically (bug)
Expected result = trill alternate note follows the alteration given by the grace note
