Code review comment for lp:~pwlars/uci-engine/tr-pass-no-tests

After further discussion, we decided this is a premature optimization. The intent of adt-run was always to fail when there are no tests in the package. If someone has a compelling reason why we shouldn't do this, then we can discuss further, but the only thing that comes to mind is that some packages may be simple enough to not need tests. I don't see any reason why we couldn't push back that an intentionally simple test could be added in this case. So... abandoning this for now unless someone has a good reason to do it.
