Bug 38082: Advanced editor does not save the selected framework

When creating a fresh record in the advanced editor, it does not
save the framework selected from the Settings dropdown.

Test plan:
==========

1. Enable the advanced editor feature (EnableAdvancedCatalogingEditor).
2. Start editing a new record in the advanced editor.  Fill in the
   mandatory fields, select a framework (other than Default) from the
   Settings dropdown, save the record.
3. Select view -- note that the record has been saved with the Default
   framework.
4. Apply the patch; restart_all; refresh the browser window.
5. Repeat p. 2.
6. Select view -- you should now see that the record has been saved with
   the correct, selected framework.
