Integration test of room metadata

[cryptix]

Something like

• go-ssb-room creates invite
• Node.js client accepts an invite from the Go server using ssb-http-invite-client
• Node.js client connects to the go-ssb-room
• isRoom happens in the background and Node.js client saves data in conn.json
• We check what was written to conn.json

Personally, I want to be sure we don't regress on this schema/format.

Yeah, and I was thinking where to specify this format. Probably best will be on the rooms2 spec but for room.metadata() once we implement that, and we can soft deprecate isRoom.
