服务列表中所有服务接口都会显示一个dubbo-admin应用的一个相同的接口

- [x] I have searched the [issues](https://github.com/apache/dubbo-admin/issues) of this repository and believe that this is not a duplicate.
- [x] I have checked the [REAMDE](https://github.com/apache/dubbo-admin/blob/develop/README.md) of this repository and believe that this is not a duplicate.

### Environment

* Dubbo Admin version: 0.5.0-SNAPSHOT develop分支
* Registry center detail (type and version): nacos 2.2 dubbo3.1
* Operating System version: mac osx 13.2.1
* Java version: 1.8

### Steps to reproduce this issue

1. 服务提供者正常启动，没有进行过重启
2. dubbo-admin上面的服务列表，每个service接口都会显示一个额外的应用名是dubbo-admin的同样的接口。

额外想问一下：如何去掉这个MockService的服务接口？
Pls. provide [GitHub address] to reproduce this issue.

### Expected Result

What do you expected from the above steps？

```
Just put your stack trace here!
```

Start by reproducing the service-list behavior on the develop branch with Nacos 2.2 and Dubbo 3.1, using the steps and screenshot in this issue. Trace how the extra dubbo-admin MockService entry is represented and determine how it can be removed. Done means the duplicate interface no longer appears for every service and the MockService behavior is clearly verified.
