Dubbo3调用配置了提供者path属性的服务提供者出现找不到提供者的报错

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

### Environment

* Dubbo version: 3.1.0 -> 2.7.5.x
* Operating System version: linux,windows
* Java version: 1.8

### Steps to reproduce this issue

1. 配置了path属性的服务提供者启动 dubbo老版本
2. 消费者启动订阅服务失败 dubbo3.1.0这个版本

Pls. provide [GitHub address] to reproduce this issue.

### Expected Behavior

感觉是dubbo3的服务消费者没有兼容path这个配置与dubbo低版本表现得行为不一样，导致序列化检查时候失败了

### Actual Behavior

If there is an exception, please attach the exception trace:

No source file or test is named. Start by reproducing the failure with a Dubbo 2.7.5.x provider configured with a path and a Dubbo 3.1.0 consumer on Linux or Windows, then inspect provider discovery and serialization compatibility; done means the consumer subscribes successfully and finds the provider.
