Fix ordering of check minimized state callback

- We previously notified the docked stack minimized changed asynchronously
  (ag/6130053) but now this is a direct call, which causes the notify to
  trigger a cancel of the recents animation, which triggers another
  notifyDockedStackMinimizedChanged() call with the new state, which leads
  to an inversion of delivered states to sysui.  Instead, always notify
  the remote listeners prior to synchronously updating the internal state.

Bug: 133243292
Test: Show the IME in split screen and try to swipe up (this should just
      dismiss the IME and not leave the user in a broken split screen
      minimized state)
