Bug 11844: Take into account itemtypes, branches, and cn_source
MARC subfields can be linked to "authorised values" that are not real
authorised values: itemtypes, branches, and cn_source.
Those were not taken into account. This patch fixes that
Test plan:
1. Create additional fields for order lines with a MARC subfield that is
linked to one of those "fake" authorised values list
2. Follow the same steps as in the main test plan
