Excluded Views don't go through Transition.

Bug 35832096

When entering or exiting Views were excluded, they were still
being set to INVISIBLE during the exit transition. This made
them disappear instantly. Instead, I've reverted back to the
original implementation by not affecting excluded Views during
the transition.

This CL walks the transition and removes excluded Views from
the enter/exit from being affected.
