GroupAdminTest.test_group_permission_performance fail on full test suite run

[otherjacob]

the test passes when running all the admin_views tests in isolation, but fails when running with test suite.

Final pass of running the test against --bisect produces this:

======================================================================
FAIL: test_group_permission_performance (admin_views.tests.GroupAdminTest)

The missing query is

  {'sql': 'QUERY = \'SELECT "django_content_type"."id", "django_content_type"."name", "django_content_type"."app_label", "django_content_type"."model" FROM "django_content_type" WHERE ("django_content_type"."model" = %s  AND "django_content_type"."app_label" = %s )\' - PARAMS = (\'group\', \'auth\')', 'time': '0.000'},

ContentTypeManager caches get_for_model() queries. Another test caches the Group content type.
