Description
Issue type
Crash or freeze
Description with steps to reproduce
- Create a score
- Add notes in voice 1
- Select note that's not on first beat
- While in note input mode, press Cmd+Alt+2 to go into second voice, and press a note name
- Open part score
- Optional: Save, close, reopen -> without this step, you get a corruption at the next step, after which you can't continue.
- In Layout panel, expand instrument, click settings icon
- Uncheck voice 1 visibility
- Save, close, reopen -> crash, because the EIDs in the score are corrupted

Additional context
This is a very fragile part of the code that has not a single test case, and is so hidden in the UI that it likely isn't tested often.
For reasons unrelated to this issue, I tried rewriting Excerpt::setVoiceVisible so that it clears the existing staff and refills it, instead of creating a completely new staff, which is wasteful and annoying, but that didn't make a difference for this issue.
