catbref f29ae656b9 More work on CHAT
Always add group 0 info to output of API call GET /chats/active/{address}.
No groupName entry as it's "no group" or "group-less" or "not group related".
Timestamp also might be omitted if no message found.

Fix output of POST /chats/compute so it doesn't include zeroed 64-byte signature.
