事务没有回滚，TM报redis异常

- [x] I have searched the [issues](https://github.com/codingapi/tx-lcn/issues) of this repository and believe that this is not a duplicate.

### 1. Bug Description
只要出发分布式事务，TM就报redis异常：

我的TM配置：
```

lettuce:

### 4. Tour Idea

Inizia da com.codingapi.txlcn.tm.core.storage.redis.RedisStorage.refreshMachines alla riga 269, quindi segui la chiamata attraverso ManagerServiceImpl.refreshMachines e EnsureIdGenEngine.onTmReceivedHeart. Riproduci il fallimento con la configurazione del cluster Redis fornita ed esamina lo stack trace di discard di Lettuce. Il lavoro è completato quando la ClassCastException non si verifica più durante la gestione dell’heartbeat e il rollback della transazione distribuita viene completato correttamente.
