Title: Disable fallback search for contact lookup

We still have a contact-for-address fallback mechanism that uses search, for ancient and decrepit contacts that predate the appropriate indexes (which were added six months ago).

I'm reasonably sure we've migrated all the contacts since then, and the additional expense of a search feeding into a mapreduce every time we look for a contact for a new address is way more than we can manage at high load.
