Improve room send tests (#1344)

- Add origin_server_ts in make_join proto events as it's a required in
  both the [make_join](https://spec.matrix.org/v1.6/server-server-api/#get_matrixfederationv1make_joinroomiduserid)
  specification and all the PDU definitions in rooms v1-v10.
- Do not require event endpoint in user setup since the tests were
  migrated to [use sync](ab34a0e)
