Fix restarting nginx in wsl:create-sites

nginx didn't allow to restart as the restart command was in a loop and resulted in

```
Feb 03 15:09:01 systemd[1]: Failed to start A high performance web server and a reverse proxy server.
Feb 03 15:09:01 systemd[1]: nginx.service: Start request repeated too quickly.
Feb 03 15:09:01 systemd[1]: nginx.service: Failed with result 'exit-code'.
```

So just restart once at the end :)
