Add cases in lmbd131 covering the following situation:

class Outer<T> {
    class Inner2<U> {}

    Supplier<Outer<T>.Inner2<String>> s4 = Outer.Inner2::new;
}

Inner2 is a non-static member of a raw type (no type arguments are mentioned in Outer.Inner2::new).

lmbd131 has already a number of tests, but I have not seen such cases in there.
