Bug 30918: Allow passing filtered record to get_marc_notes

Bug 30918: Allow passing filtered record to get_marc_notes

This patch does the absolute bare minimum to prevent private notes from
appearing on the OPAC.

Test plan
1. Go to Koha Administration -> Koha bibliographic frameworks
2. View the MARC structure for your BKS framework (or something else)
3. Search for tag 583, edit subfields
4. Go to subfield 'x' - nonpublic note. Confirm the OPAC visibility
   checkbox is UNCHECKED.
5. Edit or create a record using the BKS framework. Put a note in the
   583$x.
6. View this record in the OPAC
7. Go to the Title notes tab. Confirm the non-public note is
   showing, even though the framework says it should not be
   visible via the OPAC.
8. Apply patch
9. Confirm the non-public note is no longer visible
