Thibault Saunier e41a6b6fac ges: Rework the way we ensure core elements are not wrongly moved between clips
Instead of focusing on the instances of the clips and their children,
we relax the check to allow moving track element clip between clips
that share a common asset. This makes it as correct conceptually but
more flexible, and the code becomes simpler.
