"Cannot read properties of undefined" when trying to list applications
First off, thanks for a great plugin! Setup was very simple, and just worked out of the box.

I wanted to add switches to launch apps, so I enabled 'List applications list' in the plugin config. This throws an error when Homebridge starts:

```
[18/12/2021, 12:02:45 pm] [Living Room TV] Cannot read properties of undefined (reading 'send')
[18/12/2021, 12:02:45 pm] [Living Room TV] [DEBUG] TypeError: Cannot read properties of undefined (reading 'send')

    at WebSocketSecure.getApplications (C:\Users\tallytarik\AppData\Roaming\npm\node_modules\homebridge-samsung-tizen\lib\methods\ws.js:58:9)
```

The plugin still works fine after this error - just fails to get the application list.

The TV is a 2019 QLED (QA65Q60RAWXXY). Let me know what else I can provide to help debugging.
