Fix for a change in action_mailer that dislikes .html.erb on the (non…

…-html) email template:

  In rails 2.2, the activation email on account creation seems not to use the template, but instead is just the available variables crammed together. the attachment is an rspec test which I placed under spec/controllers. it passes in rails 2.1, fails in rails 2.2.
