LP#1930933: fix issue with over-escaping in search results title attributes

This patch fixes an issue where a record with a title containing the
word "hidden" can have its title, ironically enough, not show up
on public catalog search results.

To test
-------
[1] Create an OPAC-visible record whose 245 is something like:

    =245 04$aThe hidden one <script>alert('title!')</script>

[2] Search for the record in both the TPAC and Bootstrap skin. Note
    that the title isn't displayed.
[3] Apply the patch and repeat step 2. This time, the full title
    should be displayed.
[4] Verify that the OPAC does not display an alert box.
