Deleting a place through the UI should also disable any users which are associated with that place

[kennsippell]

What feature do you want to improve?
Deleting a place

Describe the improvement you'd like

1. Create a place in the CHT
2. Create an offline user and set their facility_id to equal that place
3. The user is never active and doesn't create any docs
4. A user manager deletes the place through the UI

Current - The user can still login. They get a profoundly broken experience. User managers spend a bunch of time trying to clean up these broken users as part of user-management investigations.
Desired - The user should automagically be disabled when their place is deleted.
