The incorrect type of mysql.column_stats caused the server during the upgrade of every other table to complain: [ERROR] Incorrect definition of table mysql.column_stats: expected column 'hist_type' at position 9 and expected column 'histogram' at position 10 to have type longblob. To prevent these verbose server errors, we upgrade the mysql.column_stats table first. Consequently limit "Incorrect definition of table mysql.*" to the appropriate set of limited test cases. The rpl_gtid_errorhandling.result changes the GTID number by one because of the added early suppression (adding a table row). Reviewer: Vicențiu Ciorbaru Fixes MariaDB/mariadb-docker#438
