* test now always pass "secure" and "httponly" options, as they are required
* could be considered BC, but [`RememberMeFactory` passes them](https://github.com/symfony/symfony/blob/2.3/src/Symfony/Bundle/SecurityBundle/DependencyInjection/Security/Factory/RememberMeFactory.php#L21), so they should've always been treated as required
* I can squash the commits before merging
* Alternative solution: #14843
