Playback: omit any number of empty chords at the end of a score

[waldyrious]

At the moment only the last one is omitted from playback.

At the moment it only makes sense to omit the last one since it's the only one with no specific chord, unless the user would "delete" the n-1 in that case he should also have the possibility to delete chords no ?

Btw i don't think this falls in the bug category

If you start drawing a chord, then for some reason you remove its notes from the diagram, the chord after that will be present, so there will be 2 empty chords at the end of the score. One would expect the playback to ignore all of them, rather than have the hardcoded assumption that there will be a single empty chord at the end of a score. This already happens with the current version of the app, and works against expectations, hence the bug tag.
