Ensured mappings work after metadata edits

I mentioned the need for some metadata edits in
1ac9f3a555c9f789ce1afe0a14ae613c7f91da18, and now that I've made
those, the mappings I made earlier appear to work properly.

This means that 33 out of the 48 elections returned by the API now
have working mappings! Hopefully the rest aren't too bad.
