When an event is registered during the tour, a link is clicked without
waiting for any result.
As a consequence, the tour stops and the browser cookies are cleaned.
This leads to random failures because sometimes the remaining requests
generated by the link click have enough time to be completed and
sometimes not.
With this commit a simple step is added, that waits for the clicked link
page to be loaded.
