Revert "Disable backfilling 1,000 messages on idle" 

Now that Zev's message list branch is merged, there's no longer a
performance penalty for loading these old messages, and it improves
our narrowing performance to have them loaded.

This code is slightly different from the original commit
93d47710891cfc4db9fa00beaa5ccd10113aa1c3 since the way to access the
first element in the message list and the API for get_old_messages
have changed since then.
