Can't add permission if permission codename conflicts
Related galaxy_ng issue: https://github.com/ansible/galaxy_ng/issues/448
The pulp permission API doesn't check the app label when it queries for permissions, which can lead to multiple permissions returned in some cases where plugins have conflicting model names.
In the case of galaxy_ng, we have a conflicting
group model, which causes the following error to get thrown whenever anyone attempts to add permissions to manage groups to a user or group.
Exception Type: MultipleObjectsReturned at /api/automation-hub/_ui/v1/groups/1/model-permissions/
Exception Value: get() returned more than one Permission -- it returned 2!
