Use st_texture_cache_load_icon_name_for_theme() so that we get the right colors for symbolic icons. The code refactoring to achieve this also avoids constantly starting a new icon load each time we set a property on initialization ... the icon is loaded only after we have a #StThemeNode assigned. https://bugzilla.gnome.org/show_bug.cgi?id=633865
