Previously, calling cancel() on an Animator would cause onAnimationCancel events to be sent to all listeners. This was confusing for listeners that were keying off this event for performing other actions, when the original animator wasn't truly canceled (because it wasn't even running, or had already been canceled earlier). This change hinges listener notification on the animator actually running; no events are sent otherwise. Also added the first set of Animator tests to verify that this behavior is correct.
