Description: fix #307929: corruption when inserting frame in front of nested frame
.
Resolves: https://musescore.org/en/node/307929
.
If you try to insert a frame in front of a horizontal frame
that itself is nested within a vertical frame,
the list of measurebases for the scores gets corrupted,
since the horizontal frame is not actually part of the list.
Solution here is to make sure we get the top level measurebase
that contains the current measurebase.
In most cases, it's the same thing,
but this will return the vertical frame in the case at hand.
