Ensure that complex generic cases are handled in name generation

[vbfox]

Complex generic / Non generic nesting should work :

class NestedTyped<T1>
{
    public class DoubleNestedTyped<T2>
    {
        public bool NormalMethod(T1 t1, T2 t2)
        {
            return default(bool);
        }

        public T3 GenericMethod<T3>(T1 t1, T2 t2, T3 t3, string otherArg)
        {
            return t3;
        }
    }

    public class DoubleNested
    {
        public bool NormalMethod()
        {
            return default(bool);
        }

        public T2 GenericMethod<T2>(T1 t1, T2 t2, string otherArg)
        {
            return t2;
        }
    }

    public bool NormalMethod(T1 t1)
    {
        return default(bool);
    }

    public T2 GenericMethod<T2>(T1 t1, T2 t2, string otherArg)
    {
        return t2;
    }
}
