How to reproduce:

1. simulate error during the rss notification (add raise 'error' to https://github.com/theforeman/foreman/blob/44539bfc73f1c36e57985707032a1c91160af799/app/jobs/create_rss_notifications.rb#L8)
2. restart the dynflowd (or web server in case of development)
3. notice that the "Create RSS notifications" (when foreman-tasks is present) in still in stopped/success
4. further notice, there is not next task planned for the next check

It turns out the active_job is not handling `after_perform` callback when rescue bock is triggered, see https://github.com/rails/rails/blob/v5.2.0/activejob/lib/active_job/execution.rb#L33-L43
