Remove empty create_and_test_config_common_properties tests

[amyeroberts]

What does this PR do?

There's a bunch of tests which have create_and_test_config_common_properties implemented, but it's just an empty check. These should be removed as they falsely indicate config properties are being run in test_config, they clutter the code and this prevents them being copied again for new model implementations

Hmm, I am not sure why this happens 😰 .

The canonical way looks like

    def setUp(self):
        self.model_tester = xxxModelTester(self)
        self.config_tester = ConfigTester(self, config_class=xxxConfig)

    def test_config(self):
        self.config_tester.run_common_tests()

I agree what is done in this PR. The above question could be left in a separate PR (when we have time)

Thank you!
