Simple tests for the Bootstrap navigation bar

This test simply checks that we've tried to put in a navigation bar
and the corresponding links.  It needs some fixing that will make it
more specific when a particular bug can be traced, but for now is
"good enough."
Fix within bug.

The within problem that was commented out now works properly with
proper refactoring.
Test login functionality.

With these tests, we ensure that the user must be logged in before
they can edit their profile and that the user is automatically logged
in when their account is created.
