// Before 0.84.2, pk table added prefix "class_" to every class's name.
// After 0.84.2, the pk table should be migrated automatically to remove the "class_".
// In 0.84.2, the class names in pk table has been renamed to some incorrect names like "Thclass",
// "Mclass",
// "NClass", "Meclass" and etc..
// The 0841_pk_migration.realm is made to produce the issue.
