Bug fix #11951 修改删除空服务实例时，服务名和分组名没有正确解析的问题

Can you help community to add unit test for this case?

It seems that a unit test already exists here：ServiceControllerTest

Yes I know it, I mean the old one only check the UpdateServiceTraceEvent , not check DeregisterServiceTraceEvent

Prefer you add the check for DeregisterServiceTraceEvent in UT.

I'm sorry I didn't understand how to write unit tests for Nacos. Do you mean to change it to this?

@Before
public void before() {
    super.before();
    subscriber = new SmartSubscriber() {
        @Override
        public List<Class<? extends Event>> subscribeTypes() {
            List<Class<? extends Event>> result = new LinkedList<>();
            result.add(UpdateServiceTraceEvent.class);
            result.add(DeregisterServiceTraceEvent.class);
            return result;
        }
        
        @Override
        public void onEvent(Event event) {
            eventReceivedClass = event.getClass();
        }
    };
    NotifyCenter.registerSubscriber(subscriber);
}

@After
public void tearDown() throws Exception {
    NotifyCenter.deregisterSubscriber(subscriber);
    NotifyCenter.deregisterPublisher(UpdateServiceTraceEvent.class);
    NotifyCenter.deregisterPublisher(DeregisterServiceTraceEvent.class);
    eventReceivedClass = null;
}
