Bug 10911: fix invalid links when displaying records that have 880 fields

Koha intranet search results using XSLT for records with 880 fields have
the details link created by a code path that incorrectly links to some
opac pages.

Test Plan:
1) Enable XSLT for intranet search results
2) Upload or create a record with at least one 880 field
3) Search for the item ( must have multiple hits to avoid redirection )
4) Click the title link, note it is broken
5) Apply this patch
6) Click the title link, note it is correct

Comment: Work as described, no koha-qa errors.

Test
1) imported two times sample record
2) reindex
3) search, find example record, broken links
4) applied patch
5) refresh, good links

NOTE: A similar (invalid references) problem is present on
UNIMARC and NORMAC files
I'll file a new bug for those cases.

Works nicely, tested with a different set of sample
records with Hebrew 880 fields.
