bug 5372: identify empty field in authority record correctly

This is the sibling to the fix for this bug for the bib
editor.  However, note that this change won't have a
direct effect yet, as currently you can't specify a
default value for a field or subfield in the authority
MARC frameworks.  See bug 4887.
