Return 0 status code on exception or invalid code

[marcingrzejszczak]

fixes gh-1382

[codefromthecrypt]

something like this otherwise you still end up with the exception :P

  @Override public Integer statusCode(HttpResponse response) {
    int result = statusCodeAsInt(response);
    return result != 0 ? result : null;
  }

Ok but statusCode is called only via the statusCodeAsInt in Brave
