    manager: move initial login handling to function
    
    After the greeter is started, we may start any pending initial-setup
    login from the user.  Right now we do that directly from
    on_display_status_changed.
    
    This commit moves the code off to a subroutine, since it's only going
    to get more complicated in the future.
