Bug 9438: biblio notes displayed when adding order

The biblio notes should not appear in the "Notes" textarea
of the "New order" page, in Acquisitions.

TEST PLAN
1) Find a biblio with a note (for example 300$a in UNIMARC, 500$a
in USMARC), or add a note to a biblio.

2) In a basket, create a new order for that title. Before the patch,
the "Notes" textarea contains the note from the biblio. After the patch
the textarea is empty.
