[BUG] Renaming platform causes crash on initialization
**Describe the bug**
Renaming my `name` config value from anything other than _Harmony Hub_ causes the plugin to crash during Homebridge initialization. The following is seen in the log output:

```

```

**Reproduce**
I upgraded to 1.0.0, and made the appropriate config migration changes. I was previously using the switches mode, but accepted the new default to use the TV mode. I then realised I should rename the platform as the TV accessory had the name _Harmony Hub_, and I wanted to to be _Living Room TV_ instead. I renamed the `name` config value and restarted Homebridge, but the plugin caused it to crash during initialization.

**Expected behavior**
I would expect the `name` value to work correctly and rename my TV accessory with no errors.

**iOS**
- Version 12.4
- Device: iPhone 6s

**Config**
```
{
    "platform": "HarmonyHubWebSocket",
    "name": "Living Room TV",
    "hubIP": "192.168.2.2",
    "showTurnOffActivity": false,
    "publishSwitchActivitiesAsIndividualAccessories": true,
    "publishDevicesAsIndividualAccessories": true,
    "publishHomeControlsAsIndividualAccessories": true,
    "mainActivity": "Watch Apple TV"
}
```
