Title [Guitar Pro] Crash on deleting a staff in imported score ⇒ Crash on deleting a staff

I can recreate with the MSCZ, not closing as duplicate of #24181 as the test looks handy, but this doesn't look like a GP problem to me.

Title Crash on deleting a staff ⇒ Crash on deleting a staff when it is involved in a part

From scratch
Steps:
1- Create a score with 2 flutes;
2- Insert notes in both staves;
3- File -> Parts... -> New All -> Ok;
4- Add -> Instruments...
5- Select the first flute -> Remove;
6- Press Ok -> crash.

Instruction staffIdx(staff) in libmscore\undo.cpp, line 690 gives -1 and this triggers the assert in the next line.
