Fixes rotation stuck in core without trigger transition.

If there exists a Open transition for an app and display was involved,
update rotation will not start any rotation neither startRemoteRotation
or requestTransition because there will add the display to sync group,
and since there never send any rotation-related signal to shell, the
display will never sync ready because the system decorations won't know
there should be an configuration change.
There should check isCollecting so it can fallback to
startRemoteRotation.

Test: enable shell transition, run atest TaplTestsLauncher3
