Don't assume that session was marshaled
Don't assume that session was marshaled

Janus incorrectly set symbol as keys and the user model class as is
in the current session object. It broke on a fresh Rails 4.1.0
application, because the session hash was no long serialized.

This commit fixes that by assuming that everything in the session is
a string (hash keys and user model class name).
