core: Unifi device trackers unavailable in 0.108

The problem

In 0.108.3 all Unifi device trackers that aren’t home during startup are marked as unavailable. They have the restored: true attribute. Once the devices reconnect to wifi, they then correctly track home/not_home until the next restart. At that point, they again become unavailable if they are away.

Going back to 0.107.7 fixes it so all devices show up as not_home after a restart.
