fix(httpreceiver): Fix double wrapped TLS listener

[BinaryFissionGames]

Proposed Change

• Always use http.Server.Serve instead of http.Server.ServeTLS

The listener returned from serverSettings.ToListener will already have TLS built in, so it strips any TLS handshake stuff before it reaches the server. Since it's double wrapped due to ServerTLS, the inner TLS handler doesn't see the handshake, and always assumes it's just getting a normal http request, even when sending an https request.
