the API of TransformMarcToKoha has changed.

For a reason I don't understand (& appear a conception bug), the biblioitemnumber is not shipped in the hash
and it's needed by the UPDATE. So it has to be reintroduced manually.
That's how it's done in Biblio.pm/Sub ModItem.

I think 3.2 will see the end of biblioitems (& it's replacement by something else)
