File corruption

Bug description

When deleting rests of voice 2 (and presumable other voices apart from the first) on a main score, a part score that solely contains voice 2 'corrupts', saying that there is an 'empty bar'.

Steps to reproduce

1. Create a new score
2. Add a part score which only shows Voice 2

3. Write some notes in voice two then delete the entire bar (on main score)

4. Observe empty bar in part score

5. Attempt to save and see this warning

I will also add this workaround: delete the bar only in the part score and hide the rest on the main score.

@mike-spa This issue is assigned to me, but isn't this exactly what you were working on recently?

[mike-spa]

Yes, indeed it is possible that this may be fixed by #23783. @oktophonie could you please also check for this while testing that PR? In any case, I'll reassign this to me
