Description
## Issue Description
Type: *bug report*
### Describe what happened
版本: V1.8.6
由于系统规则抛出时是直接抛出，没有包裹 `Rule` 对象。而在 `LogSlot` 记录日志时，会去获取 `Rule` 对象，导致此处出现 `NPE` ，使得 `SystemBlockException` 没有抛出被吞掉，使得系统规则失效。
下图是发生 `NPE` 时，导致 `SystemBlockException` 被吞掉的情况，其他限流规则是否会被吞掉，还待测试。
### Describe what you expected to happen
