[gtk+/wip/otte/gadget: 12/18] iconhelper: Use the gadget's node

[Benjamin Otte <otte src gnome org>]

commit 99182b936f57a6f15d64e74365209ee43dba5826
Author: Benjamin Otte <otte redhat com>
Date:   Wed Dec 9 18:32:05 2015 +0100

    iconhelper: Use the gadget's node
    
    ... instead of looking at the widget's style context.
    
    This removes all calls to the style context.
