> *Scenario*:
> Start two nodes, populate data, stop node, try to {{table.keyValueView().get}} value, that is not presented in the table.
> *Expected behaviour*: 
> Exception is thrown (we need to agree on the right exception)
> *Actual behaviour*: 
> We can caught {{ReplicationTimeoutException}}, {{TransactionException}}, {{IgniteException}}. Sometimes we fail with {{NullPointerException}}, the reason is because we can stop leader of some partition, and for two nodes it is impossible to elect new leader, so we get null in {{InternalTableImpl#enlist}} when we try to get {{{svc.refreshAndGetLeaderWithTerm();}}
