Bug 13904: Make unimarc_field_4XX displays usefull 200 subfield data

When searching for multivolumes titles, UNIMARC 4xx field plugin
displays the title of the biblios (200$a), without giving info about
volumes (200 $h $i). It neither doesn't display $e (subtitle) info which
could greatly help to disambiguate search result.

The displayed title is supposed to link to a biblio record view (MARC /
normal). It doesn't work.

TO TEST:

- On a UNIMARC Koha, add a new biblio record
- Call the 4XX plugin from 461/463 field
- Search for a biblio record which contains 200$e, and/or 200$h and/or
  200$i subfields.
- You get a result list, with two issues:
  1. $a, $h & $i aren't displayed
  2. Biblio title is not a link
- Apply the patch, and repeat previous steps.
