seata 0.6.0 根据demo运行示例代码，全局事务未回滚，undolog 有记录数据，但是一直没有补偿

就是纯粹的跑demo 执行rollback 后，出现id = 1002 的用户 有创建order_tbl记录， 过了一会库存表数据又在减少，查看发现undolog（库存db中的） 有数据 ，但是一直没有补偿~

Start by running the Seata 0.6.0 demo and tracing the rollback for user id 1002. Inspect the order_tbl record, the inventory database's undo_log, and the compensation-related logs; done means the rollback removes the created order and restores the inventory instead of leaving an unprocessed undo record.
