UnhandledPromiseRejectionWarning: Error: Cannot add a bridged Accessory with the same UUID as another bridged Accessory[BUG]
**Describe the bug**
I recently began to migrate my Homebridge setup from being split across FreeNAS/macOS to a unified Raspberry Pi setup with the Homebridge image. On FreeNAS, this config was 100% functional. Naturally, I copied the contents of the Harmony config, as-is, onto my Raspberry Pi, and removed the FreeNAS instance of Homebridge, where the Harmony plugin initially resided. Now, I receive the below error no matter what I do. This is the ideal config, but it is worth noting that I have the same issue, even after I purge the config.

**To Reproduce**
1) Install plugin
2) Begin config
3) Restart service

**Expected behavior**
I expected the plug-in to load error-free. I know this can be misconstrued as snooty, but I promise it's not. I'm just filling in as many blanks as I can here.
