Bug 14154: 608$9 defined twice in UNIMARC biblio-koha-indexdefs.xml

In DOM config file :
etc/zebradb/marc_defs/unimarc/biblios/biblio-koha-indexdefs.xml, the 608$9 is
defined a second time instead of 610$9.  Just a type I think.

Test plan :
- Apply patch
- Install a UNIMARC + DOM instance
- Define in a framework 610 using a thesaurus
- Create a new biblio
- Create a new authority (same type as the thesaurus defined above)
- Index : rebuild_zebra.pl -a -b -x -z
- Link the field 610 to the new authority
- Index : rebuild_zebra.pl -a -b -x -z
- In authorities search, search for the new authority
=> You see Use in 1 Records(s)
