[BUG] Some activity switches are disappearing after restart 
Dear team,

I think I have a very common issue. After installing the plugin and have it configured successfully (it is working great!), after some reboots and update to the very latest version 1.0.6, I got some of my activity switches which disapeared.
When checking the homebridge startup logs, we can see the following error:
`[2019-8-22 21:41:34] [Bern] WARNING - setupFoundAccessories - TV accessory added in your bridge, if another plugin is exposing a TV accessory this one might not be visible in your remote widget

If I delete the cachedAccessories file within homebridge accessories folder, and restart homebridge, situation gets cleaned... until next time I reboot or relaunch homebridge.

Is there some cache or something I should clean more?

Many thanks in advance!
