Added missing test for 9.2.3, non-signed-in users attempting to visit a protected page
Adding delete links to user profiles caused a bug when rendering user profiles for non-signed in users. So I forced users to sign in before viewing profiles. Supporting tests were written.
Completed 9.6.8, all tests green, redirects to profile page.
Completed 9.6.1, all tests green, used stackoverflow, comments in code
