Added the beginnings of the navigation tests

I still need to refactor the methods but at this point, all tests work

Fixed errors in spacing and refactoring out of scenario
Fixed the need of a global variable
Fixed naming issue and hopefully clicking issue
Fixed weird issue of needed to sometimes first find then click instead of css_click
