LibWeb: Save time for animationcancel event before transitioning to idle

Browse source 
The if statement in the dispatch implies we are in the idle state, so of
course the active time will always be undefined. If this was cancelled
via a call to cancel(), we can save the time at that point. Otherwise,
just send 0.
