[gdm/wip/wayland-take-2: 8/8] session: Reset immediately on cancel

    session: Reset immediately on cancel
    
    For some reason, before now, we round-tripped through the
    GdmManager object when resetting the session instead of doing it
    directly. The only time we can cancel is when the client calls
    Cancel();, so just handle that directly.
