Fix placement of newly-created 035 fields

Problem: When a new 035 field is created in the MARC SRS record, it is placed at the bottom of the variable fields instead of with the other 03 or 0xx fields of the record

Steps to Reproduce:

1. Log into FOLIO-snapshot-load as diku_admin
2. Go to Data Import and load the attached file using the secret button
3. View the newly-created MARC records in the log or in Inventory/View source record
4. Find the newly-created 035 field

Expected Results: Newly-created 035 field should be with all the other 035s (or all other 0xxs) at the top of the record, in field order within the 0xx fields

Actual Results: It's at the bottom of the record, just above the 999 ff
