[FIX] point_of_sale: tour waits for everything to be loaded

Before this commit, the first step of the tour pos_basic_order
waited for something not precise enough, and that was true
before anything was loaded

After this commit, we wait both the the webClient and the Chrome to be loaded
with a more specific selector
