Using ui-control to show/hide groups for users behaves incorrectly

### Current Behavior

When you use the `ui-control` node to control the visibility of groups for different users, when the page is loaded, the group visibility is cached based on the last user that viewed the page. Once the page is refreshed, the correct group visibility for the current user is reflected.

Note that this behaviour only affects groups. Visibility of pages works as expected.

### Expected Behavior

The correct group visibility for the logged in user is used immediately, without needing to refresh the page.

### Steps To Reproduce

1. Configure a dashboard with an admin only page and an admin only group, (as per the guidance at https://flowfuse.com/blog/2024/04/building-an-admin-panel-in-node-red-with-dashboard-2/). For the purpose of this reproduction, assume there are two users, "alice" and "bob", and configure the dashboard so that only user "bob" can see the admin page and group.
2. Log in as bob, and the admin page and group **is** visible.
3. Now log out of bob and log in as alice. When alice's dashboard first loads, the admin page is correctly hidden but the admin group **is not** hidden.
4. Refresh alice's dashboard, and the admin group will now be hidden.
5. (Optional) Log out of alice and back in as bob, and initially the admin group will be hidden, but after a page refresh the group will be visible.
