peristsCookies parameter not passed from methods to _httpRequest

[genesiscz]

All of the head, get, patch, delete, post, put methods do have a persistsCookies parameter but they do not get passed to _httpRequest

  static Future<dynamic> delete(String url, {headers, timeoutSeconds = DEFAULT_TIMEOUT_SECONDS, json = false, persistCookies = true}) {
    return _httpRequest(HTTP_METHOD_DELETE, url, headers: headers, timeoutSeconds: timeoutSeconds, json: json);
  }
