OS: Windows 7 SP 1 (6.1), Arch.: x86_64, MuseScore version (64-bit): 3.0.1.4971, revision: 6d522ee

Steps:
1) Grand staff Template, and organize the time signatures like this (no matter if it's C, or 4/4 or Cut time, in second position - image below)
2) Generate parts

3) Drag and drop C time signature, or Cut time, in the measure indicated with 4/4 time signature.

Result: crash

I have a piece in 4/4, into which I need to add a single of bar of 2/4. As soon as I add the 2/4, the time signature is presented twice. I have tried all combinations of the order in which I insert the signatures, and I get the same error each time. See bar 58 of the attached. When I open the file, the single 2/4 is shown, but as soon as I save the additional 2/4 gets shown. On the 'choir' part the duplicate signature is shown at file open.

fix #281504: fix issues with replacing time signatures with equal duration

These issues include:
- Replacing 4/4 to C leads to a crash in score with parts if there
is another time signature after 4/4 (see #281504).
- Replacing 4/4 to C leads to a crash in the same configuration
without parts if MM rests are enabled.
- Replacing 4/4 to C on MM rest has no effect (in situations where
it does not lead to a crash).
- Adding a time signature from palette after creating parts
produces time signatures which are not linked between parts and
master score. This also breaks replacing equal duration time
signatures in this case.
