Previously we had to click on the Gerrit comment posted by Regres to
unfold the single-line snippet into the full comment, to check whether
any regressions occured. This change makes "--- No change in
test results ---" come first so we can see at a glance without opening
the full comment that no regressions have occured, or be informed about
changes in test results.
