- Add call to unregister for remote animations from the system when the launcher activity is destroyed to prevent a lingering reference from the system to the old activity. But separately, to not have to wait for the system to GC before clearing the binder ref, we also wrap all runner implementations so that they can be cleaned up after a GC in our process only.
