One partner, one district.

The form used to ask for a home region AND a coverage set, which put the same
partner in `partnerinfo.applocationid` and several `partnerlocations` rows. A
partner works one district — that is the operating rule — so the two writes
carry the same single id and `regionsOf` is what guarantees they cannot
disagree.
