Moq1200 incorrectly firing on overridable member

[rjmurillo]

Analyzer Moq1200 is incorrectly firing in the following case

public interface IFoo
{
  Task<bool> DoSomethingAsync();
}

var mock = new Mock<IFoo>();
mock.Setup(foo => foo.DoSomethingAsync().Result).Returns(true);

The analyzer indicates the Setup should be used only for overridable members; however, this member is on an interface while the error only makes sense if the method is on a class.
