Nil Pointer access on timeout using retry #58
Description
When a request interrupts due to a client timeout and when using a retry condition function then the underlying resty.Response.RawResponse is nil. Which is pretty obvious because the remote haven't sent any. But one has to make a nil check on the RawResponse in RetryConditionFuncs because functions like resty.Response.StatusCode() access directly the underlying RawResponses fields.
