Upgrade from 1.9.3 to 2.0.5 - Cannot add TV to HomeKit
I upgraded the homebridge-webos-tv from v1.9.3 to 2.0.5; after which I am unable to add the TV to the Home app.

Homebridge: v1.1.6

Config: 
```
		{
			"platform": "webostv",
			"devices": [
				{
					"name": "Great Room TV",
					"ip": "192.168.1.82",
					"mac": "78:5D:C8:C4:50:97",
					"keyFile": "/var/lib/homebridge/LGTV.webostv.keyfile",
					"notificationButtons": [
						"Doorbell - Ding Dong"
					]
				}
			]
		}

```

The homebridge log shows:

After restarting HomeKit - I noticed that the TV showed up as a Light Bulb in the "Great Room". I choose to ungroup the accessories, this created several buttons in the room related to the TV; at this point there was a TV accessory. I removed the TV from HomeKit thinking there might be left over registration stuff causing all the other buttons to appear. After removing the TV from HomeKit, I restarted homebridge successfully, I attempted to re-add the TV to HomeKit, however, HomeKit does not find the TV. 

I've tried several things, including:
- removing the config from the config, restarting homebridge, re-adding the config and again restarting homebridge. 
- re-naming the TV in the homebridge config (then restarting homebridge). 

The TV does not appear in any other room. 

From my iPhone running iOS 14.0.1, in the Home App, I am attempting the following:
1. From the Great Room room, clicking the "**+**" icon and choosing **Add Accessory +** 
1. On the **Add Accessory** panel, touch the **I Don't Have a Code or Cannot Scan** button
1. On the **Select an Accessory to Add to <Home Name>** panel, the spinner appears, but no accessories appear. Touch the **My Accessory Isn't Shown Here**
1. On the **Accessory Not Shown** panel, touch the **Enter code...** link
1. On the **Enter HomeKit Setup Code** panel, enter the 8-digit code from homebridge and touch **Continue** button
1. Back on the **Select an Accessory to Add to <Home Name>** panel, the spinner appears, but no accessories appear.
