Title: Raise an exchange error if we can't ship all requested items

This will prevent an exchange from failing silently when, for example, a stale return authorization admin page gets submitted requesting an expedited exchange for an item for which there is no longer any stock available.

If this looks good I'll submit upstream as well.
