acq search: line item detail search fields work only for LI search

The various line item detail search fields (copy ID, barcode) are included in the general acquisitions search forms for all core search types, but work only when searching for line items. When searching for POs, SLs, or invoices, the presence of a line item details search field will cause the search to fail.

There's no functional reason for that to be the case; the line item attribute search fields work for all search types.

This is a long-standing bug in the Perl search code, which isn't adding the necessary joins between acqlid and the core search record type if the core type isn't 'jub'.
