title: interceptFrom and interceptSendToEndpoint not working
body: <p>I was trying to intercept from/to specific rabbitmq route something like the following,
  interceptFrom(rabbitmq:localhost/someExchangeName?queue="somerRabbitMqQueueName").to("log:hello");</p>
  
  <p>and i'm not getting anything there.</p>
  
  <p>I've tested
  intercept().to("log:hello") and i can confirm it's working, can anyone let me know if there's something else that i need to configure to make the intercept from/to works?</p>
