Bug 10961: Error in GetMarcBiblio can cause severe data loss

Browse source 
A bug in GetMarcBiblio can cause severe data loss if your database has
records where the biblionumber and biblioitemnumber do not match and the
script misc/batchRebuildBiblioTables.pl is run.

The Biblio::GetMarcBiblio makes a kall to
C4::Biblio::_koha_marc_update_bib_ids which passes the biblionumber as
both the biblionumber *and the biblioitemnumber*.

Thus, if your biblio and biblioitem numbers are not always equal, you
will end up with a record where the biblioitemnumber is incorrect in the
record!

This is usually not a severe issue, but since batchRebuildBiblioTables
uses that record to update the database tables, it ends up updating the
wrong biblioitem row!

NOTE: What a horrible, horrible typo that was. Tested this with the
      second patch.
