Fixing controller state is not properly cleared when the animaiton is cancelled.

This was leading to a pending animation running while the state had changes,
leaving user in an inconsistent state.

Various atomic animation fixes
> Ensuring that there is only one success listener on atomic animation, so that atomic
  controller is created only once and to the final mToState
> If atomic controller is already running, skip animating the atomic conmonenets as
  part of main animaiton
> Cancel atomic controller if it is going to a different state
