修复: 热更层IActorMessage应该继承IMessage

Unity/Assets/Hotfix/Module/Actor/IActorMessage.cs

 // 不要在这个文件加[ProtoInclude]跟[BsonKnowType]标签,加到InnerMessage.cs或者OuterMessage.cs里面去
 namespace ETHotfix
 {
-	public interface IActorMessage: IRequest
+	// 不需要返回消息
+	public interface IActorMessage: IMessage
 	{
 		long ActorId { get; set; }
 	}
