Unhandled system.campaign_updated events go straignt to the fail queue #132
Description
When sending events to the "delivery" queue (use case: double opt-in sync with CleverReach), not only the expected supporter.email_status events (eventType: "supporter.email_status") are added to the delivery queue.
There are also "campaign updated" events ( eventType: "system.campaign_updated") which are not handled with proca-queue.
It leads to constant nacking and requeuing of such messages. Nacked messages pile up in a fail queue, and it is almost impossible to distinguish them from messages backed for other reasons.
We need to upgrade proca-queue to handle these messages.
To reproduce run npm run start -- -e hateaid, change any hateaid-test campaigns, and check the 981 fail queue.
