[Maniphest] [Closed] T23: login with flask_fas_openid fails with "Strange state: failure"

This is being filed as a retrospective, it's already been fixed.

It turns out that this only happens to users who are members of many FAS groups (more than 17 - that was the highest number of groups for a successful login that we know of).

Not exactly sure what the absolute root cause of this is but adding the following configuration value for flask_fas_openid.py seems to have fixed the issue

PREFERRED_URL_SCHEME='https'

Fix has been applied to stg and prod through puppet.
