This isn't done. A bunch of other things need fixing.

Posting this for feedback before I go do a lot of work that might get ditched.

feedback?
This test was failing because it was calling `.values_dict()` which no longer returns all the fields. Now it returns just the `_type` and `id` if you have nothing set to be stored in the mapping. If you have stuff in the mapping set to be stored, then this will return whatever you have stored.

Instead of changing the mapping (which requires a reindexing), I lazily specified the fields that were being tested against. I don't know if that invalidates the test or not.
