Fix flakiness of testTaskChangeCallBacks

1. The test asserts that there will be onDetachedFromWindow. But if
   finishAndRemoveTask is called too early before the window is
   attached, there won't be the callback. So make sure that
   onAttachedToWindow is called before triggering the removal.
2. The task removal callback may come from previous test. So only
   count down the latch for removal if the incoming task id is the
   one created by the current test method.

Also
 - Create virtual display only if needed.
 - Replace deprecated callback of TaskStackListener.
