Bug 24918: Fix attribute mappings in Koha::Acquisition::Basket

When bug 18731 was written, the official vote on the RFC hadn't been
held yet. Once it got voted, the mappings were adapted and all the
dependent work fixed as well. But three attribute names were overlooked
and they become evident on developing 20212 which required them.

This patch fixes this really tiny mistake.

To test:
1. Just verify the voted attribute names.
