Fix transition to the wrong location on screen.

- TaskStackLayoutAlgorithm currently depends on the launch state to 
  calculate the right bounds, which means that the launch state has to
  be set before the call to getThumbnailTransitionActivityOptions().  
  When double-tapping quickly, we would use the old launch state which
  would cause us to calculate the wrong bounds.
