[FIX] web_tour: native events + better error messages

This commit is two-fold:
 1) events triggered with jQuery do not go through the native
    layer, so if an handler has been bound natively, it won't be
    called. Since our new code no longer uses jQuery, this caused
    issue in some tours.
 2) this commit explicitely logs the failing step when a tour
    crashes, which helps debugging.
