Also update manage profile state after a transition finishes

- When you start a swipe gesture, a transition to home is started
  which in U w/ ShellTransitions enabled will resume the home
  activity (vs. just starting it pre-U), as a result, if the user
  just taps or swipes back down without committing to going home
  the transition will finish without SysUI updating the work profile
  state again.
