Fix AnimationTest#testRunAccelerateAlpha

Bug 6419421

Remove the checks for the animation start time, because animations
do not necessarily start on the next frame. Just make sure that
the animation reports that is has started. This is done by the
AnimationTestUtils#assertRunAnimation call still in the test.
