    manager: split automatic login handling out of set_up_greeter_session
    
    Automatic login handling doesn't have a whole lot to do with the
    greeter session, so having it in setup_greeter_session is a little
    weird.
    
    This commit splits set_up_greeter_session into two functions,
    set_up_greeter_session and set_up_automatic_login_session, and then
    changes the caller to call the right one depending on if the display
    should do automatic login..
