fix broken auto-refresh (apache#25950)

In PR apache#25042 the merged change included a bug that prevents the page
from auto-refreshing if there are anything other than manual runs on the
page. We also want to auto-refresh for scheduled runs.

I've also added more complete unit tests for the expected behaviour.

(cherry picked from commit 37ec752)
