Bug 27749: Phase out jquery.cookie.js: Search to hold

This patch modifies the "search to hold" process for patrons and clubs
so that the newer jquery-cookie plugin is used instead of jquery.cookie.

To test, apply the patch and locate a patron in the staff interface.

 - From the patron checkout or details page, click "Search to hold" in
   the toolbar."
 - Perform a catalog search which will return results.
 - On the search results page you should see a "Place hold for..." link
   with the correct patron information under each result.
 - In the toolbar above the search results you should see a "Place hold"
   button with a dropdown menu which also references the patron you
   selected.
 - Test that each option works to place a hold for your patron.
 - Test that the "Forget..." menu option works to remove "place hold
   for" options.
 - Test that your "Place hold for" option is also remembered on the
   bibliographic detail page.

To test the changes to Patron Clubs:

 - If necessary, create a patron club:
   https://koha-community.org/manual/20.11/en/html/tools.html?highlight=club#patron-clubs
 - Add one or more patrons to the club:
   https://koha-community.org/manual/20.11/en/html/tools.html?highlight=club#enrolling-a-patron-in-a-club-from-the-staff-client
 - From the patron clubs page, choose "Search to hold" from the club's
   "Actions" menu.
 - Perform the same tests above.
