bug: Owl-bot post processor check missing in PR from python-dialogflow

[parthea]

In this PR from python-dialogflow the owl bot post processor didn't run. I've seen the owl bot check run successfully in another PR that I reviewed. How do I go about troubleshooting why the owl bot check was missing? I triggered the post processing check to run by adding the label owlbot:run so we don't block the API feature from being merged.

@SurferJeffAtGoogle, I've labeled this as a docs issue, but feel free to relabel as appropriate.

I expected owl bot post processor to run, but it never did.

@parthea @SurferJeffAtGoogle I see OwlBot post processor having run on both those PRs shared, to dig into this I believe I would need to see a PR where the problem was fresh, i.e., it hadn't already been merged without the post processor having run.

I dug into the specific issue having trouble, and the reason owlbot:run did not run on subsequent runs was that the branch was deleted.

Please let us know in chat if this happens again, and we can look at the build history and see why the trigger failed.
