You have the server returning 202 accepted and HttpConduit treats the 
case with 202 and no body, when no async mode is enabled, specifically 
and does not initiates the client message observer, but also losing the 
in message which contains HTTP response headers.

I think, for now, we can do a minor fix in HttpConduit to ensure that 
the response message is attached to the exchange in such a rare case - 
the headers should be visible to the receivers such as an RS client 
expecting the untyped Response.

I'm not sure about running the client observer in this case though, 
might optionally be done (example, by having a property set) if needed 
in the future


Thanks, Sergey
