[heycam/webidl] "call a user object’s operation" should not have an optional argument in the middle (#534)

That makes callers ambiguous unless they use rather elaborate wording to get around it.

This is about _opName_.

Now, having said that, do we actually need _opName_. We don't want folks to use callback interfaces. Those in DOM only have a single operation (although they both do list _opName_, maybe it wasn't always optional). Are there any that have more than one operation?
