Code review comment for lp:~canonical-isd-hackers/canonical-identity-provider/session-refactor-email-sent

I like avoiding the use of session for this (+1)

- tiny stylistic issue: we prefer singular assertion methods (assertEqual)
- l. 249: always use RequestContext, otherwise context processors won't be applied (you won't get a style page for example)

One last question: given that there were certain precautions not to break the openid dance in this view, are we certain not redirecting will keep those scenarios working?
