Bug 29539: UNIMARC: authority number in $9 displays for thesaurus controlled fields instead of content of $a

When you try to dislpay a bibliographic record on unimarc that has subjects
linked with authorities then only the $9 is displayed as link instead of the
content of $a and it's subdivisions, if any.

To test:
1) You will need to have a bibliographic record with at least one subject
autority connected in unimarc framework.
2) View that record on OPAC on detail display. The subject will display as
a number ( $9 )  and you cannot see the text/term of the subject ( $a )
3) Apply patch
4) Repeat step 2
5) The subject display in a normal way based on content $a - or more subfields
