/api/v1/conversations: empty Account

Installation type (OTP or From Source): sauce
Pleroma version (could be found in the "Version" tab of settings in Pleroma-FE): latest dev

This endpoint always returns empty account in "last_status" field, This is unexpected by the clients and leads to errors.

Also, accounts field of Conversation entity is also empty list. I'm not sure if it should be like that, when conversation have only one participant.
