    fixes GB#619826 TST: for search & history, don't clean-up search terms
    
    * TST was trying to be smart by cleaning-up  search terms
      (removing non-alphanumeric characters) before using them to
      query as well as before storing them in history.
    * This change allows TST to send the search terms as-is to
      tracker-store, but as for history, it first strips both leading
      and trailing whitespace, while also applying normalization.
