Title: fix query port for rust and 7d2d protocols

Hi!
Thank you for support "Rust" and "7 Days to Die" games.
But it's not working for me.
Because I think there was a bug with query ports for those games.
query_port = port + 1,
but you used
```php
$this->port_client(($this->port_client() - 1));
```

I fixed it and test this changes. Now rust and 7d2d servers working fine.
Please take my pull request.
Thank you!
