Several app transition fixes:

> If launcher already started, creating the state transition only after threshold crossed, so that previous animations are not cancelled
> Not posting animaiton callbacks at the front of the queue, as that sometimes causes it get executed before onNewIntent
> Farking the activity as forceInvisible while launching an opaque app, so that quickly pressing home/back runs the reverse animation
> Not running state animations when force-invisible is true
