erp5_catalog:[DEBUG] Use migration method to update SQL Method objects

This was needed because of the problem being faced while debugging,
so maybe when we finally migrate, we need to remove/modify this
function.

Imho, the better way would be to migrate everything(Catalog, SQLMethod,
PythonScripts) all in one go instead of separately doing this.
