Deployment notifications seam to be broken

[db-it]

Plan notifications work fine, but no message appears in Google Chat if a notification for a deployment with type one of DeploymentFinishedNotification, DeploymentStartedAndFinishedNotification, DeploymentFailedNotification is configured.

Configuration example:

.notifications(new Notification()
    .type(new DeploymentStartedAndFinishedNotification())
    .recipients(new AnyNotificationRecipient(new AtlassianModule("org.lummerland.bamboo.hangouts-notification:recipients.hangouts"))
    .recipientString("webhook-url")));

This notification config on the other hand works with the same webhook on a build plan:

.notifications(new Notification()
    .type(new PlanFailedNotification())
    .recipients(new AnyNotificationRecipient(new AtlassianModule("org.lummerland.bamboo.hangouts-notification:recipients.hangouts"))
    .recipientString("webhook-url")));

Bamboo version: 8.0.4
