Fix mismatch in Transition ID/instances

Bug 14597573

In a Transition, when a View is removed from a Scene
and that View has an ID in common with another View
in the end Scene, it will be matched, even if the
View in the start Scene already had a matching View
by instance. This CL prevents a match by ID when an
instance match is available.

Future: disable matching when two views have the
same ID.
