Concert pitch lossy transposition (recent 0.9.6 branch regression)
Steps to reproduce bug
1. Open Song for Dad 2.mscz . Notice the C-sharp in measure 13, top staff
2. On the toolbar, press "Concert Pitch"
Expected behavior: First note of measure 13, top staff should be a F-sharp (perfect fifth below C-sharp).
Actual behavior: First note of measure 13, top staff erroneously displays a G-flat.
MuseScore version: r. 3227 nightly build (0.9.6 branch). Transposition works as expected in 0.9.6 stable.
