The previous changes to move EthernetStateListener and
InterfaceStateListener introduced 2 separate ArrayTrackRecords. This
test explicitly uses a single TrackRecord for both callbacks, so their
respective ordering can be tested.
This change resets EthernetManagerTest to the last known good state
(57fdd00cc7).
