This is 100% repeatable for me.

1. Start ath running in dev mode.
2. Run nightwatch src/test/js/failing.js
3. If you want to see it again, you MUST restart ath.

You will see on step 5 it redirects to run '3' when it should be '2'.

HOWEVER for subsuequent runs of failing.js, it works properly. It's only on the first run of failing.js after the ath is started. No idea what is going on here and I havent replicated it outside of ATH.
