tests: Update subclass-native2.py for __new__/__init__ refactor.

Now case of subclassing tuple works, and list is broken, see comments.

tests/basics/subclass-native2-list.py

+class Base1:

+class Clist1(Base1, list):

+
+a = Clist1()
+print(len(a))
+# Not compliant - list assignment should happen in list.__init__, which is not called
+# because there's Base1.__init__, but we assign in list.__new__
+#a = Clist1([1, 2, 3])
+#print(len(a))
