Bug 13938 - Staging MARC records for import fails

It appears that bug 8970 has introduced a bug where a MARC file uploaded
for staging fails to import *unless* a matching rule is selected.

Test Plan:
1) Apply this patch
2) Stage and import a MARC record *without* choosing a matching rule
3) Note the staging works as expected
