Bug 32674: Fix placing a hold at the OPAC for serials

Placing a hold at the OPAC explodes with a 500 when the record is a
serial
DBIx::Class::Storage::DBI::_dbh_execute(): DBI Exception: DBD::mysql::st execute failed: Column 'biblionumber' in where clause is ambiguous at /usr/share/koha/lib/Koha/Objects.pm line 394

Test plan:
* Create a serial subscription for an existing bibliographic record
* Place a hold on this record at the OPAC
