Grouper Midpoint Connector Group Delete Issue

From an Internet2 community member, they were able to reproduce in two environments:

"We did run into one issue that I can also replicate in the workbench. If you create a group and add a couple users, wait long enough for everything to propagate to midPoint, then go back into Grouper and delete the group using the UI it will cause a fatal error in the async task causing it to close.

As far as I can tell, Grouper will put messages on the queue to delete each user, then put a group delete message last. It looks like midPoint will attempt to retrieve details on the deleted group through the connector when processing the first member delete message in rabbitmq. Since the group no longer exists on the Grouper end it throws a fatal error."
