Fix T73056: Cache not invalidated in fade operator

This operator is written in python it is inserting keyframes to create fade
effects.

Add Sequence.invalidate() python function to invalidate strip if it is
changed in python.

Perhaps I could implement cache invalidation to actual curve manipulation.
I guess it wouldn't be very hard to do but having means to invalidate form
python is useful as well.
