Can't remove stale accessory
### Current Situation

I am using the nest plugin, the thermostat stopped working in HomeKit and the 'accessories' section of Homebridge UI. After messing around with it for a while I converted it to a Child Bridge, once that new bridge was added to HomeKit the thermostat started working.   

However the old instance of the thermostat was still there as not responsive in Apple Home, it was also still there and non functional in the 'Accessories' page of HB UI.  I couldn't see two instances of the thermostat in the cached accessories dialog, so went ahead and used the 'delete all cached accessories' option just incase it was lurking somewhere.  However it's still there.

In the config.json there is no mention of the Nest in the main config, it's all moved to a child bridge instance as far as I can tell.  Any idea how I can get rid of this?
