Bug 1032749 - [testing] Test that an Existing User can Delete Profile

Added test works fine on merging pull for updating css selectors. https://github.com/mozilla/oneanddone/pull/153
I should have noticed this before, but this is a bit inaccurate. The page that one is redirected to after clicking `cancel` is in fact the Home page. There is no actual User Dashboard Page. There is just the home page, which displays the dashboard if the user is logged in and does not display the dashboard if the user is logged out.

I think we need to reorganize the pages so that the User Dashboard is just a region of the home page. We could make it a property of the home page and the home page could include logic to either return the User Dashboard if the user is logged in, or return nothing if the user is not logged in.

I know this sounds a bit wonky, but I really don't like the fact that this current code suggests that the user is being redirected to a  different page when `cancel` is clicked, whereas the user is in fact being redirected to the Home page.
