Review Comment:
How can zero or any arbitrary value, created from thin air, can be a valid
for a `enlistmentConsistencyToken`?
Original values for `enlistmentConsistencyToken` are obtained from
`primaryReplica.getStartTime()`
(See `SqlQueryProcessor::primaryReplicas(IgniteTable)` ).
Maybe I am missing something but this is far from obvious.
