### Ⅰ. Issue Description
Raft 模式下 RM 开启事务空指针异常，请问是我的配置有什么问题吗？
### Ⅱ. Describe what happened
`SeataClusterContext.getGroup()` 计算结果为null，导致 rm 开启事务失败。

RM 可以正常启动事务

不是上面说的那个问题，你这个堆栈不对，理论上应该是RaftCoordinator.exceptionHandleTemplate,而不是AbstractExceptionHandler.exceptionHandleTemplate
一个节点是不能正常使用raft模式的，不要在一个节点下进行测试
store:
mode: file -> raft
你为什么不按照raft示例里的配置来？

group: jlpay -> default
因为客户端侧的按group负载均衡没做，所以默认的请求都是按default分组请求上来，导致出现npe
