Bug: Resending notification when one trigger has failed

[olegsu]

I have created the following argocd-notifications-cm with subscriptions:

      subscriptions:
        - recipients:
          - slack:some-channel
          trigger: custom-trigger

Then I've added another recipient: - email:[email protected], the notifier YAML is not updated, yet.
As a result, the controller keeps sending the slack notification because the SMTP was not configured yet.
I think it is because of the missing annotation that the controller adds to the application.
A fix can be either to add the annotation, logging the fact that not all the notifications have been sent. Or, to create annotation per recipient.
