Without cleaning host_port and device_port attribute of event client, there will be a caught exception during teardown_class process. Because the event client and snippet client will clean up the port forwarding configuration for the same port.
This problem occurs whenever the user uses an async RPC. But this exception will be caught, so it won't cause the test to fail.
