The culprit is the
LiveServerAddresstest case. ParentsetUpClassis called 8 times (becauseraises_exceptionmanually calls it), whiletearDownClassis called only one time. So we have 8settings_override.enable()balanced by only onesettings_override.disable(). Consequently, the settings object we get inteardown_test_environmentis one of the overriden settings instance, not the initial one, hence the absence of_original_allowed_hostsattribute.
