    overview: Switch to the apps page when startup is completed if needed
    
    Trying to switch earlier than this might result in the shell staying
    in a funny state, that causes strange effects and bugs, such as showing
    windows in something like the window picker mode (but that it's not
    properly initialized) or preventing the DnD operations from working
    due to the wrong hierarchy of visible Clutter actors hanging off the
    root stage object.
    
    Also, don't show the overview at startup if windows are visible, which
    could cause some also funny situations when restarting the shell.
