[gnome-shell-extensions/wip/fmuellner/alacarte-compat: 3/4] apps-menu: Minor code cleanup

[Florian Müllner <fmuellner src gnome org>]

    apps-menu: Minor code cleanup
    
    The parameter to _clearApplicationBox() has never been used, so
    remove it. In fact, modern javascript makes the function so compact
    that we can just move the code inline.
    
    Fixes https://gitlab.gnome.org/GNOME/gnome-shell-extensions/issues/27
