Multiple Instances of everything!
Hi! I just installed this plugin to target one of my two Hubs. That hub has 5 activities:

- Listen to Music
- Blu-Ray
- Apple TV
- Shield TV
- Nintendo Switch

However, after adding it to my HomeKit this shows up:
![img_8383](https://user-images.githubusercontent.com/25128243/51778522-fa7acf80-20b6-11e9-9e66-ca1e03aa15dc.jpeg)

I have 3 instances of "Apple TV" and multiple of the rest. Only one of the "Apple TV" switches work. The rest do nothing. 

Here is my config file:

```
{
    "bridge": {
        "name": "HomebridgePi",
        "username": "CC:23:3D:E4:CE:32",
        "port": 51464,
        "pin": "031-45-157"
    },
    "description": "This is an example configuration file. You can use this as a template for creating your own configuration file containing devices you actually own.",
    "accessories": [],
    "platforms": [
        {
            "platform": "HarmonyHubWebSocket",
            "name": "HarmonyLivingRoom",
            "hubIP": "10.0.1.32",
            "showTurnOffActivity": false,
            "refreshTimer": 30
        }
    ]
}
```

Here here is the log:
