Several problems were causing animations to jump to the end when
launching an app while a previous app was animating away.
- Keep the two app token lists in tighter synch. These were separated
when we hoped to completely separate layout form animation. This is
not as critical a goal any more.
- Use new test criteria for starting and stopping animations.
Bug 7885350 fixed.
