Fix autoplay stop issue

Bug fix: Keep the carousel autoplaying if auto=small value (eg; 1000) and orientationChange happens.

When the old transition-property is equal to the new one, Webkit will not trigger a transitionEndEvent. So I check if the old and the new one are equals and I call transitionEnd handler.

bug seen on chrome@Android 4.1.2 and stock@android 2.3.6
