When StateSync() runs and triggers Untrack() on items
that have just been removed from the state but on which
Untrack() is underway, the operation tracker would be
reset to phase queued and in some cases stay so.
Also happened for Track()
This caused failures of TestClustersPin as SyncStatus()
is triggered regularly while Tracks() and Untracks() happen.
