MotionEvent#ACTION_CANCEL after the map is destroyed

[LukasPaczos]

I've run into the MotionEvent#ACTION_CANCEL being dispatched by the Android framework after the map is destroyed and in this case, we've been clearing core transitions, which is unnecessary.

com.mapbox.mapboxsdk.MapStrictModeException: Map detected an error that would fail silently otherwise: You're calling `cancelTransitions` after the `MapView` was destroyed, were you invoking it after `onDestroy()`?
