Run test error about aiogrpc

[hubo1016]

This is a correct behavior. This test case covers the situation when the request stream or response stream raises an exception inside the iteration. When these exceptions occur, grpc.io core generates this log.

It might be possible to drop this log with a customized logger, but maybe it is not necessary?

Maybe we can modify the message to "Testing raising an exception inside GRPC service"?

Feel free to create a pull request, or I can do it myself later.
