Fix jobs-related bug in task conversion

While working on some other code, noticed a bug in the jobs code. We're
adding job version after we're checking if there are port configs.
Before, if there were no port configs, the job version would be missing,
because we would return before trying to convert.

This moves the jobs version conversion above that code, so we don't
accidentally return before it.
