**Describe The Bug:**
After using `sudo hb-config` to enable ssl/https redirection as described in the wiki, the nginx config gets destroyed. 

**To Reproduce:**

Use `sudo hb-config` to enable ssl/https redirection as described in the wiki.

The following is shown on the console:

```
Synchronizing state of nginx.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable nginx
Starting Nginx...
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.
```

Moreover, `sudo nginx -T` shows the following:
```
sudo nginx -T
nginx: [emerg] unexpected end of file, expecting ";" or "}" in /etc/nginx/sites-enabled/results:3
nginx: configuration file /etc/nginx/nginx.conf test failed
```

The file `results` didn't exist before using the `hb-config`. I used `ls /etc/nginx/sites-enabled` before and there was only the `homebridge.local` file.

`cat /etc/nginx/sites-enabled/results` shows:
```
1
2
```

In the `/etc/nginx/nginx.conf` the following will be included:

`include /etc/nginx/sites-enabled/*;` 

Therefore, the file is broken. 

Deleting the `results` file and using `sudo systemctl start nginx` is the solution for this issue. Afterwards, the following will be shown and the service is working as expected with https redirection:

```
sudo systemctl status nginx

```

**Expected behavior:**
The nginx service should restart properly and the `results` file shouldn't break the config.

**Environment:**

* **Homebridge Raspberry Pi Image Version**: I used the `Raspbian-Homebridge-v1.0.3.zip`
* **Node.js Version**: v12.16.3
* **NPM Version**: 6.14.5
* **Homebridge Version**: 1.1.0
* **Homebridge Config UI X Plugin Version**: v4.20.0
