Bug 13145 UNIMARC 610 tag isn't displayed in OPAC when there is no $9 subfield

On OPAC detail page, subject fields are not displayed when they are not linked
to authorities ($9 subfield). This is due to a misplelling in UNIMARC XSL
detail page.

TO TEST:

(1) On a Koha UNIMARC, find out a biblio record with a 610 field, without $9
    subfield. Something like:

    610 1 $a Aliment -- Approvisionnement -- Europe -- Histoire

    Or add such a field to an existing record.

(2) Check that OPACXSLTDetailsDisplay is set to 'default'

(3) See this record on OPAC detail page. You must see 'Subject: ' => nothing
    after the 'Subject' label. If your record contains several 610 fields
    without $9, the | character will appear, separating no content.

(4) Apply the patch.

(5) Reload the page seen at step (3): subject is displayed now.
