Avoid waiting for drawn window without change

For example, an app is launching with starting window when keyguard
is showing. Then the transition will abort because there is no
visibility change. And then after keyguard prepares to dismiss
(keyguardGoingAway) right after the previous transition
(i.e. unlocking), the drawn starting window will be collected again.
Then the starting activity becomes no drawn window. It needs to
wait until the app is drawn.
