Revert "Tests for ensure_authenticated middleware, if the request.isAuthenticated() returns false - it redirects to the login page"

This reverts commit 6a7a3dc422f2a09e738d564dfc9e3aa54137d762.
The real, ensure_authenticated tests... ignore previous hack commit / back out :)

Also added more flavor to the mock http server, now with more express "middlewares" + passport.
