Description

With the latest addition of _cookieJar for HTTPClient, the _cookieJar is initialized as nullptr, but no check before accessing it exists (for example in generateCookieString).
This means (unless it is explicetely set) we are running in a nullptr exception/panic at this point

Sketch

HTTPClient client;
client.begin("https://google.com/);

if (HTTP_CODE_OK == client.GET())
{
  // Do Stuff
}
