On iOS (iOS 9 beta 4) I've setup a home, which contains 2 accessories.
In the Watch simulator and on the real device running watchOS 2 beta 4, the list of homes from `HMHomeManager.homes` is always empty.
Even after the delegate method `homeManagerDidUpdateHomes()` is called, the list of homes is empty.
The watchOS app has the correct HomeKit entitlement.
Is this a bug in watchOS 2 beta 4 or am I missing something?
