Bug Description

bug 996773 is happening again. The previous fix for that bug is in place, but, as before, running these two tests in order (--load-list) will cause the test to fail.

lp.services.webservice.tests.test_wadl_generation.SmokeTestWadlAndDocGeneration.test_wadl
lp.bugs.tests.test_bugchanges.TestBugChanges.test_change_information_type_using_api

Here's the failure information.
