    main: defer startup until we know our session mode
    
    commit 92083eaf76fc7a5c2ecdd182896583ab5026ddf0 made
    session mode loading an asynchronous operation.
    
    Aspects of the session mode aren't known immediately at
    start up. For instance, sessionMode.isGreeter returns
    false for greeter sessions until the asynchronous
    operation completes.
    
    This commit defers start up processing until the session
    mode is fully known.
