    loginDialog: hide authprompt when VT switching away
    
    The authprompt is no longer useful if the user isn't
    on the VT, and it's not what the user is going to
    ultimately see when they come back (they'll see the
    user list), so we should hide it.
    
    Fixes a bug where it briefly blinks in view on
    VT switch.
