Adding MARC modifications to single record imports creates broken records

Overview:
Steps to Reproduce:

1. Log into Morning Glory bugfest
2. Go to inventory and select import using the "OCLC with MARC modifications" option and import OCLC number 31934425
3. The record should import successfully and the title will have received an obvious MARC modification
4. Attempt to overlay the same record with the same OCLC number.

Expected Results:

Overlaying the record works. The MARC is modified as described in the profile and the instance and SRS are updated.

Actual Results:

The instance is not updated. A modified SRS record is created but still has the original OCLC 001 and 003. QuickMARC will not work on the record.
