Clone db failed in MariaDB 10.7.3.

[Mohammad Ali Mehdizadeh]

In MySQL8, It seems mysqldump value of column-statistics is enabled by default but MySQL documentation said another thing.
Anyway, when I add --column-statistics=0 to __clone_db, I can run tests and cloning database works well.

Thanks for the report, however it works for me with MariaDB 10.7.3 (you don't use MySQL).
