Bug: 2 Garage Doors show up in Home app
<!-- You must use the issue template below. -->

**Describe The Problem:**
<!-- A clear and concise description of what the issue is. -->
For the past couple of months, the Home app shows 2 garage doors despite only having 1, with 1 set of door sensor and hub. The myQ app works flawlessly, and one of the doors in the Home app works without a hitch. 

I first noticed when I would ask Siri to open/close the garage door and she'd respond asking which one. I only recently thought of renaming the one that doesn't work, and have noticed that all the phantom open/close notifications I've also been receiving are only coming from the renamed one.

I've removed homebridge-myq from my system, restarted, and added it back but 2 garage doors continue to show up in the Home app: 1 that works great, and 1 that doesn't do anything other than send me phantom notifications which are extremely annoying.

Any ideas?

**To Reproduce:**
<!-- Steps to reproduce the behavior. -->
