Summary: In the past, Cognito sign-ins were intended to give authorization to some AWS services (like SQS); various tokens were stored in the session for this purpose. This is no longer used. Profiles from Cognito now serve a limited purpose: first-time initialization of name and picture, and keeping track of which login method was used. For these remaining needs, ScopedSession is sufficient. Test Plan: Existing test pass. Tested manually that logins work with Google and Email + Password. Tested manually that on a clean database, name and picture are picked up from a Google Login. Reviewers: paulfitz Reviewed By: paulfitz Differential Revision: https://phab.getgrist.com/D2907
