This test was disabled by crrev.com/2616228 since the test was flaky.
This is because the RootWindowDeskSwitchAnimator fails to take a
screenshot due to the remove animation starting after the test ends.

This CL re-enables the test and fixes it by using the RemoveDesk()
fcn from desks_test_util.h instead of DesksController::RemoveDesk().
This makes the test wait for the desk remobal animation.
