Fix classmethod tests with Python 3.13+
Fixes #259 The failures were: =================================== FAILURES =================================== _____________ TestCallingOuterClassMethod.test_class_call_function _____________ self = <test_outer_classmethod.TestCallingOuterClassMethod testMethod=test_class_call_function> def test_class_call_function(self): # Test calling classmethod. Prior to Python 3.9, the instance # and class passed to the wrapper will both be None because our # decorator is surrounded by the classmethod decorator. The # classmethod decorator doesn't bind the method and treats it # like a normal function, explicitly passing the class as the # first argument with the actual arguments following that. This # was only finally fixed in Python 3.9.

For details see #160 However, Python 3.13 reverted the change from 3.9, so this adds an upper bound for the conditionals. To make the conditionals easier to read, the if-else branches were switched.
