Bug 30133: Avoid calling c->objects->search twice

Bug 30133: Avoid calling c->objects->search twice

Calling this twice sets double pagination headers, which messes up the page for the requests and
retrieves on ly the end of the list

This patch simply avoids a doulbe call

TO DO: must implement same for Biblio->pickup_locations and cover with tests
this also returns all as needing override
