Problem description: Previously when setting one of the Auto-login and Auto-logout options into "checked" state the other one was set into "unchecked" state automatically (if it was checked previously) in user create or update views in Administration => Users. 

After one of very recent merges this is not working anymore and it is possible to set both checkboxes into "checked" state having an inactive Auto-logout input field.

Steps to reproduce:

1. Login as Admin
2. Navigate to Administration => Users
3. Open any existing user with "Frontend access" = "System default" or press button "Create user"
4. Attempt to set both "Auto-login" and "Auto-logout" checkboxes into checked state.

Result:
It is possible to set both "Auto-login" and "Auto-logout" checkboxes into checked state. Due to this it is possible to have an inactive Auto-logout input field when the Auto-logout checkbox is checked.

Expected:
If one of these checkboxes is being set to "checked" state the other on should be unchecked (like it was working recently - see attached gif).

Example:
