Comment 21 for bug 1187433

I've pushed a branch to http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/collab/miker/another_metabib_ingest_fix-with-upgrade that includes the two modified functions and a modified "now run this" note. I've included a suggestion to use Dan's metabib.reingest_metabib_field_entries-only reingest method.
