    serverRoomManager: Fix runtime warning
    
    The callback to the GtkCellRendererToggle::toggled signal used different
    names for the 'path' parameter in parameter list and function block,
    whoops. It turns out that this error made the checkbox work correctly,
    as we already handle the GtkTreeView::row-activated signal, which is
    also emitted, to toggle the checked setting. Toggling a boolean twice
    is clearly not what we want, so just remove the faulty signal handler.
