[kumavis]

What happened:

Viewing dashboard, see incorrectly alerting alert in an alert panel.
clicking on the alert enters the edit panel screen for that alert, and immediately brings up the following modal

Do you want to delete notifier with invalid ID: undefined from the dashboard JSON?

this panel with its alerts are provisioned here

What you expected to happen:

• alerts to go to "not alerting" when parameters are within the range
• to not get an unprompted modal for notifier deletion

How to reproduce it (as minimally and precisely as possible):

What you get if you run:
curl http://<user>:<password>@<host>:<port>/api/alert-notifications/uid/USY-LmRGz?
This modal appears when the dashboard JSON refers to a deleted notifier.

What do you mean by "incorrectly alerting alert"?
