Temp disable test_admin_sets_not_existing_quota_type

I need to temporarily disable this test because it is checking for the wrong exception type. The quotas validation patch[1] fixes this call to return the proper 400 error code instead of a 500. Once the validation patch has merged, we can re-enable this test with a corrected exception fix.
