Comment 10 for bug 1828859

This review [1] is wrong, it builds on a wrong presumption that [2] does something it doesn't. Based on that [3] is just a workaround, but it doesn't fix the original issue.

The original issue is, that python-tempestconf doesn't take into account that tempest_roles might be a list, therefore this condition [4] is wrong.

Give me some time, I'll send a review to fix that within today.
