core/syncstate: Remove UserAction `Done` status

  When we introduced required user actions, we specified a `Done` status
  which was meant to communicate the end of the user's action to the
  GUI.
  However, we actually chose to remove those actions from the list
  instead but we left one case were the `Done` status was used.

  This could leave the suspended synchronization status active even
  after a user action was done and give users wrong expectations.
