No provider Exception after write or delete configurators

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

### Environment

* Dubbo version:
* 提供者：2.7.12
* 消费者：3.0.0-SNAPSHOT
* Operating System version: ANY(win, mac)
* Java version: 8

### Steps to reproduce this issue

注册中心：zookeeper，按接口注册模式

1. 启动服务提供者、启动服务消费者、消费者定时调用服务，调用正常；

2. 向zookeeper写入DemoService的权重修改配置
```
String url = "override://0.0.0.0/org.apache.dubbo.demo.DemoService?category=configurators&dynamic=false&weight=200";
registry.register(URL.valueOf(url));
```
此时消费者端短线短暂的No provider available
```
