Pickup measures and key changes split notes and chords into two on theorytabs

The exact same bug as this one but it only happens on theorytabs

@Vaz, thank you. I pushed the 2.16.2 build of the hookpad player to production which resolves this.

EDIT: 2.16.3 fixes this for pickup measures also.

@chris chords still split into two across a pickup measure
