Deselecting any field in the user read policy will break the user page

### Describe the Bug

By deselecting any field in the user read policy, I would expect that that selected field hasn't become available and thus the field is hidden for the user with said policy.

However, if I deselect just one field, suddenly all users are gone, (but the count is still correct)

### To Reproduce

1. Create a policy with app access and recommended settings (which provide read access to all users)
2. Assign the policy to a role
3. Create and add a user `A` under this role
4. Create and add a user `B`
5. Login with `A`; you should see user `B`
6. Remove the `token` field from the user read policy
7. As user `A`, you can't see any user now
