Use all subfield values to link authority records to bibs

Given an Evergreen instance with two authority records loaded, one
being a more specific than the other via a repeated subdivision subfield,
we must make sure that we use all the bib-supplied subfield values when
attempting to auto-link to the correct authority.  Otherwise, the "shorter"
authority record may be selected as appropriate, and data in the bib record
would be lost.
