    mainWindow: Fix updating user-list button counter
    
    Since we now update the counter in ChatroomManager::active-state-changed,
    we no longer need to do the same in ::active-changed; however we should
    properly initialize the counter in the constructor to not miss the case
    where we don't open any rooms at all on startup.
