<groovy/> sets empty Response in the Response flow, when exc.getResponse() == null

[rrayst]

This leads to

            <groovy>
                println exc.getRequest().getUri()
            </groovy>

producing weird 200 OK responses in error cases.

(This is due to:

api-gateway/core/src/main/java/com/predic8/membrane/core/interceptor/AbstractInterceptor.java

Line 136 in 3e20594

exc.setResponse(response);

)

@t-burch Test and post how the wired response looks like (test with curl).

I do not know if we should change something. Cause this might not the only Interceptor. Maybe we should check in the Transport if response==null and then provide an error message?

In what circumstance does it set the 200 OK response, how can one reproduce that
