Fixes #2744

Testing

See referenced issue commit: #2744 (comment)
All unit test pass.

A test 5.0.5-2745 RPM was build and installed successfully.

As this PR requires an sssd setup, a current omission in my test environment, I'm not able to test this adequately as it is my understanding that we only use dbus-python when interacting with sssd for its users/groups.

I was able to create & delete both a user and group using the PR RPM instantiated install.

@FroggyFlox & @Hooverdan96
I propose that we merge this to avoid hold-up of our pending Python/Django updates and from a quick look there doesn't appear to have be any breaking changes in this update (from changelog) - bar some Python 2 specific calls types. I would have expected them to error out during my exercise of users.py however, as they were removed: which should have broken the generation of a pyc file during the initial Python parsing of users.py.

We can then get testing channel feedback from folks that do have working sssd setups.

Agreed. Thanks a lot for that work!
