push-to-pull-request-branch doesn't add a comment at all when there is no activation comment (e.g. schedule trigger)

[dsyme]

(Have a fix for this, creating tracking issue here)

When running a workflow using safe output push-to-pull-request-branch running from a schedule dispatch I'm seeing

1. No activation comment is pushed (that's OK, it's a schedule trigger not a pull request comment trigger)

2. But then no comment is pushed as part of the actual apply of the safe output

I see this in the log

The "No activation comment to update (GH_AW_COMMENT_ID not set)" seems to indicate that adding a comment was skipped entirely because there was no activation comment
