[JENKINS-31446] Test Result table sorts incorrectly after three clicks of "Duration"

On a "Test Results" page, I can click on the "Duration" column heading to sort by test duration descending. I can click a second time to sort by duration ascending. However, after clicking a third time to toggle back to sort by duration descending, the order is not correct. For example, I'll see values like "1 min 24 sec" come after values like "9 sec"

Start at the Test Results page and reproduce the Duration-column behavior by clicking the heading three times, using the reported values such as “1 min 24 sec” and “9 sec.” Trace the junit-plugin code responsible for that table sort, then verify that the third click restores correct descending duration order.
