Description
RubberDuck.Refactor.ExtractInterface gives rise to some methods of the the interface class having no parameters in the method declaration if the originating method has optional arguments.

In the implementation inserted in the class from which the interface was extracted, the method signature does include the parameters but omits the Optional clause in the signature.

This is apparently also an issue with Implement Interface, and ParamArray is also dropped.
