prepare_cgi_additional_field_values needs to consider a field value as empty, because a MARC get field will always be submitted empty, and then picked up and handled by set_additional_fields accordingly.
But because we don't want to polute the database with tons of empty additional fields if many empty repeatable fields were submitted in the UI, the check for empty value still happens, but only after the MARC get check has happen, not before.
