Uncheck sibling and Hierarchical term with no result

Problem/Motivation

When the ShowSiblingProcessor is activated, if you check a term with no result, and then try to uncheck it, the url is no good. The facet parameter is repeatedly passed in the url.

This is probably due to the fact that setActiveState(TRUE) is not set for terms without results.

Proposed resolution

Add "setActiveState(TRUE)" to the item if value is present in url.
