Disable the code to check external permissions in UIC.
Background
As a part of working on T401712, we made UIC to check the viewer's external permissions on wikis when presenting the active wikis. However, it led to a significant increase in the card loading times, especially as there's a suspicion that the external permissions aren't cached properly: T405559.
Acceptance criteria
- UserInfoCard assumes that the viewer has no special permissions on the external wikis.
