Mobile: Update Facebook integration to use strict redirects
Note: This ticket was cloned for Mobile. We do not know if the mobile app is affected but someone needs to look into the code if we are doing facebook authentication with the same mechanism described below. The deadline for the facebook change has already passed so our facebook authentication can change at any moment.
As a learner, I want to use facebook account registration and login, so that I can make it easy for users to sign up for and log in to edx.
Verify that our Facebook authentication approach meets the 'Strict' requirements.
See for mobile details for what was found on the server side.
