Bug 37231: (Bug 34940 follow-up) Highlight logged-in library in facets does not work with ES

The highlight logged-in library in facets feature does not work with
Elasticsearch.  This is because facet_title_value contains an additional
" (count)" information and so gives negative results in comparisons made
in facets.inc  (line 107).

Test plan:
==========
1. Have a test installation with Elastiscsearch.
2. Set system preference 'DisplayLibraryFacets' to 'both home and holding libraries'
3. Perform a seach that will find items of your logged-in library.
   In KTD, search for 'branch:CPL'
4. Check the facet (home and holding libraries) of your logged-in
   library is not highlighted
5. Apply the patch ; restart_all.
6. Repeat p. 3.  Check the facet (home and holding libraries)--you
   should see your logged-in branch highlighted now.
