    gdesktopappinfo: Add missing annotations
    
    Add missing (allow-none) annotations to
    g_desktop_app_info_launch_uris_as_manager(). Tested with
    
      python -c "from gi.repository import GLib, Gio; 
Gio.DesktopAppInfo.new('gcalctool.desktop').launch_uris_as_manager([], None, 
GLib.SpawnFlags.SEARCH_PATH|GLib.SpawnFlags.STDOUT_TO_DEV_NULL, None, None, None, None)"
    
    which is necessary to do a launch_uris() without leaking stdout.
