Code review comment for lp:~nskaggs/reminders-app/autopkgtest

When I run the test directly on the phone:

dpkg-deb -x ubuntu-ui-toolkit-autopilot_0.1.49+14.10.20140715-0ubuntu1_armhf.deb /tmp/x
PYTHONPATH=.:/tmp/x/usr/lib/python python3 -m autopilot.run run -v reminders

I get

15:12:31.398 DEBUG credentials:83 - Creating the Evernote account.
15:12:31.576 DEBUG credentials:111 - Setting credentials to account.
15:12:31.604 DEBUG credentials:122 - Processing session.
Traceback (most recent call last):
  File "/tmp/tests/autopilot/reminders/credentials.py", line 133, in _process_session
    session = Signon.AuthSession.new(identity, method)
TypeError: Argument 1 does not allow None as a value

I didn't see that in my previous run with launching autopilot from "outside". This might be a side effect of using phablet-shell?
