Tempo changes aren't timed properly in swing

Issue type

General playback bug

Description with steps to reproduce

1. Add swing
2. Add a swing rhythm
3. Add a fermata or tempo change on the upbeat
4. Notice unexpected playback

Expected behavior: Musescore would wait until the swinged upbeat to change tempo
Actual behavior: Musescore seems to ignore the swing and change tempo on the straight upbeat

See attached video for an exaggerated example.
