`/turnServer` doesn't specify error when homeserver has no TURN server #1795

Issue

In the spec, it does not tell homeservers what to respond with for requests to /voip/turnServer when there is no TURN server configured. Currently:

Synapse and Dendrite return 200 OK with an empty body.
Conduit and Construct return empty strings for username and password, and an empty array for uris.
Telodendria does not support this endpoint yet.

What would be the correct behavior? The empty body, an (M_NOT_FOUND) error code, or something else?
