Fix X-Total count for Tire search results

In link_header.rb, the collection that gets passed to the method is either a Mongoid::Criteria (when accessing the /organizations, /locations, or /services endpoints), or Tire::Results:Collection when getting search results. The former responds to "count" whereas the latter responds to "total_entries."
