sql_safe_updates breaks Galera 4

Details

    Description

      Built in Galera 4 cluster management is broken with sql_safe_updates enabled:

      2019-12-28  4:00:44 2 [Warning] WSREP: Wsrep_schema::execute_sql() failed, 1175 You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column
      		 
      SQL: DELETE FROM mysql.wsrep_cluster
      		 
      2019-12-28  4:00:44 2 [Warning] WSREP: Failed to store view

      Also, instead of DELETE FROM, shouldn't it be TRUNCATE anyways?
