[FIX] web_tour: correct automatic click on links

Previous implementation was checking if the element we want to click
on is a link and if this is the case, only forced a redirection. This
had been done because the redirection was not working by simulating a
click, but in fact it works, the click simulation only had to be
improved.

Also, only forcing a redirection is wrong as some links have both a
real redirection link and a event handler binded to them.
