[jobcespedes]

Describe the bug No event handler is trigger when using inheritAppConfig and ClassSerializerInterceptor

To Reproduce Steps to reproduce the behavior:

1. Start the microservice application with inheritAppConfig: true.
2. Set Serializer as Global Interceptor with app.useGlobalInterceptors(new ClassSerializerInterceptor(app.get(Reflector)))
3. Emit an event order.updated
4. See that function with decorator @EventHandler('order.updated') is omitted
5. Comment out Serializer as Global Interceptor with // app.useGlobalInterceptors(new ClassSerializerInterceptor(app.get(Reflector)))
6. Emit an event order.updated
7. See that function with decorator @EventHandler('order.updated') is triggered

Expected behavior All functions with decorator @EventHandler() are triggered
