Do we stop adding an authority URI to subfield 0 if there is a string in the subfield t of a 700, 710 datafield?

[jgreben]

E.g. This is to avoid creating something like

<bf:Work/><bf:identifiedBy><http://id.loc.gov/authorities/names/n50033000>

When the work is actually "Don Camillo e Don Chichì," or whatever is in the subfield t, which is something without an existing identifier other than the title string.

 <marcxml:datafield tag="700" ind1="1" ind2="2">
            <marcxml:subfield code="a">Guareschi, Giovanni,</marcxml:subfield>
