Invoice field mapping: Vendor is not being saved

Overview:  When a vendor is selected and added to the invoice field mapping screen, it is not saved. Reproduces on folio-snapshot and the Folijet Rancher env

Current workaround: None

Steps to Reproduce:

1. Log into FOLIO-snapshot as diku_admin
2. Go to Settings/Data import/Field mapping profile
3. Create a new field mapping profile for incoming record type = EDIFACT, FOLIO record type = Invoice
4. Go to the Vendor name field
5. Click the Organization lookup button
6. Search for GOBI, and select the GOBI vendor
7. Make sure the vendor field is populated in the field mapping profile
8. Save the profile
9. Edit the newly-saved profile, and check the Vendor name field

Expected Results: The vendor name should be there

Actual Results: The vendor name is not there. The field can be populated and the profile can be saved, but the vendor name isn't saved.
