Steps:
1. Logged-in to Horizon as admin.
2. Created user "barsik".
3. Then edited project named "services": added "barsik" as "_member_" and "admin" there.
4. Logout.
5. Logged-in as "barsik".
6. Go to Identity -> Projects.
7. Set project "services" Enabled=False by checkbox.
 Get red popup Error: Not authorized to do this operation. It`s quite expected to be not able to do this.
 Cancel action by "X" button
