Subject: [PATCH] Add a check in `postSlide` for unslick. because `postSlide`
 was running after animation, it was posssible for the method to re-enable
 auto play moments before destroying the slide, leaving any `asNavFor` targets
 with two timers advancing them, and no way to clear the timer.

fixes #1031
