http interception responseError missing request

[kobelb]

According to the HttpResponseError types the responseError interceptor should have access to the request. However, responseError only gets the request when one of the response handlers are hit, because this then hits

kibana/src/core/public/http/http_setup.ts

Line 164 in de5c452

current = (await interceptor.response(httpResponse, controller)) || httpResponse;

This line

kibana/src/core/public/http/http_setup.ts

Line 150 in de5c452

let current: HttpResponse;

somehow makes TypeScript not pick up on this, I assume because anything can be undefined? If we change this line to let current: HttpResponse | undefined; then we start getting type errors.
