* origin/pr/178:
  Fix data type issue

Pull request description:

I missed *one comma* in my earlier pull request for adding a Kicksecure template, so what should have been a one-item tuple got treated as a string. This bug is specifically in the line `if self.template.flavor in ("kicksecure-17"):` - if `self.template.flavor` is anything that is "in" the string "kicksecure-17", it will cause the Kicksecure code path to be followed incorrectly. Most notably `"" in ("kicksecure-17")` will resolve to True, i.e. an empty string will trigger this. To fix the bug, add a comma just after the `"kicksecure-17"` bit so that Python can figure out this is a tuple and not a string.
