Policy - clean up access to user profile image uri

Summary: Ref T7094. We already had and were mostly using "needProfileImage" on the people query class. Only real trick in this diff is deleting a conduit end point that has been marked deprecated for the better part of 3 years.

Test Plan: clicked around the people action and profiles and calendars loaded nicely.
