Title: Navigation remove jump to footer - accessibility

When using screenreader on mobile devices clicking on `all sections` button will focus on `back to top` button because link is set to `#footer-nav`. This is done for navigation without JS.

So the solution is to change it after we know that JS is used.

I also included unit tests for the navigation.
