Subject: [PATCH] Bug 19640: fix OPAC IdRef webservice display

The OPAC webservice IdRef display was broken.
The call returns results but citations where empty.
Maybe the webservice has changed.

This patch corrects the fetch of datas in result.
Also fixes a small HTML missing tag tr.
Also adds a comment with link to official doc :
http://documentation.abes.fr/aideidrefdeveloppeur/index.html#MicroWebBiblio

Test plan :
1) Enable system preference IdRef
2) Choose an existing PPN like 032581270
3) Look result on : https://www.idref.fr/services/biblio/032581270.json
4) Call in OPAC website : /cgi-bin/koha/opac-idref.pl?unimarc3=032581270
5) Without patch you see only one role containing empty rows
6) With patch you see all roles with correct rows

Amended: removed unused @unimarc3 (not to be confused with $unimarc3).
