[BasicUI] Handle the new parameter "staticIcon" (openhab#1998)

When set on a sitemap element, Basic UI ignores the item state when
initially requesting the OH icon and do not request it again when the
item state is updated.

Depends on openhab/openhab-core#3735

Related to openhab/openhab-android#3404
