Prevent caching of result by making pre-check url and runner url unique

Somehow after a while tests start to return some sort of cached results.

To battle this sort of caching (because it causes mistrust of tests) I shuffled around the reset code. I also made the `kill_konacha` reset and remove the Capybara session. This helps in that you can now use `reload konacha` if you would run into this cache issue.

I also changed the `session.visit` and `runner.run` urls that they are not the same anymore.
