IconHelper: Avoid warnings for non-existing stock ids

Browse Source 
There are some registred stock ids like gtk-discards that have no icons,
and you could also pass a non-registred stock id. Both of these means
gtk_style_context_lookup_icon_set returns NULL, which causes
a critical in gtk_icon_set_render_icon_pixbuf.

We avoid this by just making these render as EMPTY.
