(core) Remove LoginSession, which was mainly serving situations that are no longer used.

Browse Source 
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.
