Title: PLA-310 -- ignore visualization info language value

Sometimes WikisModell::getVisualization info provides a blank value for 'lang', which overwrites the more trustworthy value from the search result. This pull request updates logic in Wikia\Search\ResultSet\Grouping::setHeaders to avoid deleting the language value of a grouped search result.
