If the session has something instead of a token there will be a fatal error when `$this->refreshUser($token)` is called because the argument on that method is strictly typed.

Refs #5267

Adds the following configuration

```

```

Which allows the configuration of the session not to use any save handler and therefor just use whatever save_handler is set in `php.ini`
