Void method shouldn't need explicit given clause.

[hainayanda]

So I have this kind of routing protocol:

protocol MyViewRouting {
    func routeToSomeView()
}

I just want to verify that ViewModel is calling routeToSomeView() method once but it will throw a fatal error unless I do something like this which feels unnecessary since it's a non-throwing void method after all:

given(router) .routeToHome().willReturn()

I think in this scenario, this given shouldn't be required at all.
