Flip the order of the emit-job-header tests

This more accurate reflects how this is run by opendev. Note this is not
strictly necessary to get in as the post-logs.yaml playbooks determine
where things are uploaded anyway. However, this may be slightly easier
for people to read in logs if things line up more closely to each other.
