   ### Bug
   - Which version of SkyWalking, OS and JRE?
   6.1
   - Which company or project?
   use rabbit `@RabbitListener` in spring project,  the code like this:
   
   ```java
       @RabbitListener(queues = "aaaa")
       public void handlerMessage(String message) {
           //  there will invoke dubbo service
       }
   ```
   
   It should be one trace like:` rabbitmq-producer -> rabbitmq-consumer -> dubbo`
   but in fact, I got two trace: `rabbitmq-producer -> rabbitmq-consumer ` and `dubbo`

   I have find the reason: 
   the rabbit producer InstanceMethodsInterceptPoint was `com.rabbitmq.client.impl.ChannelN#basicPublish` , it will call at `AMQP Connection` Thread, But `@RabbitListener` method will call at other thread, So the trace will divide two trace
