Revert first and should fix for server stream and check only for Triple protocol.

hi i don't know what your mean about fix for server stream and check only for Triple protocol，Because of only tripe protocol had protobuf method ,I think check whether if triple protocol is not necessary

1. For triple's stub, Server Steam will create two method.
2. For Dubbo protocol, protobuf serialization is allowed and you can use protobuf message as a data trandfer object in network.

i found tri protocol,if the provider create two stream method like below,invoke streamserver method will invoke the wrong method,is this a right behavior
`public interface DemoService {

GreeterReply greet(GreeterRequest request);
void greet(GreeterRequest request, StreamObserver<GreeterReply> streamObserver);

}`
