BibEdit: Holding Pen fix

• record_order_subfields was called for the HP but in a case not for the record that is returned to the gRecord. So the subfields were not sorted and as a result the comparing algorithm returned wrong results in some cases.

• The fields of a tag of gRecord are not sorted alphabetically, but before applying the comparison algorithm on client side the records' fields were sorted, resulting to conflicts in some cases. Removed the sorting part from client side.
