Environment

• Dubbo version: all
• Operating System version: all
• Java version: all

Steps to reproduce this issue

1. create two ReferenceConfig for same service with different configuration.
   <dubbo:reference id="demoService" interface="com.alibaba.dubbo.DemoService">
   </dubbo:reference>
   <dubbo:reference id="demoServiceAsync" interface="com.alibaba.dubbo.DemoService" async="true">
   </dubbo:reference>
2. startup the consumer application.
3. get the ConsumerModel from ApplicationModel.

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

Expected Result

ApplicationModel.allConsumerModels() should returns two ConsumerModel.

Actual Result

ApplicationModel.allConsumerModels() only returns the first ConsumerModel.

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

With future investigation, ReferenceConfig cannot put the second ConsumerModel as they are in same serviceName.

Also, this is the same issue for provider with below configuration.

<dubbo:service interface="com.alibaba.dubbo.DemoService" ref="demoService">
</dubbo:service>

<dubbo:service interface="com.alibaba.dubbo.DemoService" ref="demoService2">
</dubbo:service>
