Protect mock with lock to fix flakiness, add two tests to presubmit
AppWindowTokenAnimationTests and DisplayContentTests are no longer
flaky. Removed the annotation respectively.
The fix of WrongTypeOfReturnValue flakiness works, as in
787b244dbb0a5b43e3b5b95dc1cf347ca8ae1400. Apply the fix to two more
cases.
