This test executes SYSTEM RESTART REPLICAS, that may leave some tables
in some tests, and the problem test is
01414_mutations_and_errors_zookeeper, that has invalid values in the
table that produces the following error:
2022.06.19 19:02:07.165320 [ 1242562 ] {} <Error> MutateFromLogEntryTask: virtual bool DB::ReplicatedMergeMutateTaskBase::executeStep(): Code: 6.

And if this table will be left, then checking error messages in
/var/log/clickhouse-server/clickhouse-server.backward.clean.log will
fail, like in [1].
