incorrect appname in dubbo-admin

消费者归属应用是unknown，实际找到这些 ip 的时候这些应用已经设置过dubbo.application.name了
注册中心是 nacos

The report identifies incorrect consumer application ownership in dubbo-admin when using Nacos, but names no source file or test. Start by reproducing the lookup with a consumer whose dubbo.application.name is set, then trace how the Nacos data is read and mapped to an application. Done means the configured application name is shown instead of unknown.
