Bug 23210: login4tags should be a link and included in every search result

TEST PLAN:

1. Make sure TagsEnabled and TagsInputOnList are set to allow.
2. Don't be logged into the OPAC.
3. Make a search and notice the 'Log in to add tags' text is not a link
   on the results page.
4. Apply patch
5. Refresh OPAC results page
6. 'Log in to add tags' takes you to the login page.
