[wm] schedule a traversal when animation ends

When a window animation runs, we boost the frame rate to
max, overriding any framerate that the app sets. We were missing
an update to window framerate which meant after a screen
rotation, the app would be stuck at  the max framerate.
Fix this by scheduling a traversal when the animation ends.
