Don't panic if FetchReplications gets a url.Error

If FetchHTTP() suffers a lower-level error, it will return an err that is not an instance of APIError. In such cases, the daemon currently panics, which isn't a great response. Instead, it should properly handle the error up the stack and retry later.
