Describe the problem

After SET CLUSTER SETTING server.eventlog.enabled = false, CREATE SCHEMA fails desc validation:

demo@127.0.0.1:26257/defaultdb> create schema s;
ERROR: schema "s" (104): expected matching namespace entry, found none

To Reproduce

Change the cluster setting and try CREATE SCHEMA via SQL.

Expected behavior

CREATE SCHEMA works regardless of setting value.
