Currently if you delete an Ansible integration in Morpheus it will orphan any Ansible automation tasks that utilise that Integration.
After deleting (and re-adding) Ansible Integration X, if you attempt to run an Ansible task Y that utilised X, it will fail, and in the Morpheus UI logs you will see the message "no account integration for ".
To fix this, edit task Y, assign the correct new Ansible repo and then save Y.
