Bug 20811: (QA follow-up) Prevent calling AddItemBatchFromMarc and ModBiblioMarc without biblionumber

If you use -update but do not find matches (or did not want to match), you
should not call those routines. We should warn and skip this record.

Adding a warn at the start that the choice of options may not be smart.
Note that this needs further attention somewhere else. You could mix
-update with -insert for instance and still see some problems. (May depend
on items with unique barcode etc.)

Test plan:
Run -update without match or isbn.
Or run -update -isbn with a non-matching ISBN.
