Review comment:
I don't think we reach here if it is a REFRESH table, so logging an error is
fine. But maybe adding an explicit check or assert will be useful? We can get
to this logic in one of two ways:
1. Broker receives an EV update
2. Broker receives a HELIX message (TimeBoundaryRefreshMessage) sent from
the controller.
