ACQ order upload use copy location from owner

When uploading an ACQ MARC order record, attempt to match copy locations
to copies based on the copy owning location instead of the upload
context org unit.  This allows one branch to order copies for another
and have the copies use the copy location of the other (owning) branch
(when they exist) instead of the ordering branch (or parent org).

AutoFieldWidget support external copy loc retrieval

When rendering a collection of copy locations, AFW fetches locations
relevant to the context org unit.  While rendering an AFW for an
existing object, though, whose copy location is outside of that scope,
the code will now append the non-local copy location to the selector and
tag it with the owning lib (to avoid dupes).
