bugid: 99764 -- fix case sensitivity issue in go-search

The refactor last week took away Wikia\Search\Match classes' ability to interface directly with instances of Title. This resulted in the logic in WikiaSearchController's handleArticleMatchTracking method to rely on Wikia\Search\Config::getOriginalQuery. Because we were creating instances of Title based on this value, we were creating incorrect lower case title instances.

This updates the workflow to access the appropriate instance of Title via an Article created from the ID assigned to Wikia\Search\Match\Article.
