Lineitem copies (details) were set to be sorted by branch ('owning_lib')
by default. However this was not happening because the lineitem_details
'owning_lib' referenced a fieldmapper object (not an id or name).
This submission sets the owning_lib to the shortname so that sorting can
occur in the intended way.
