The "website_gray_color_palette" tour recently failed 4 times during
staging build on runbot, out of those 4 caught times, it seems that:
A) 3 were because the last step was marked as failed too soon
(screenshots and logs seem to indicate the editor was still loading).
B) 1 was because of a "random" asset error (traceback when lazy loading
the editor JS).
The cause of (B) was not found and should be later investigated if seen
again. This commit tries to avoid (A) which is probably related to a
known issue: when the website iframe has to reload it may sometimes take
more time than is allowed by the default timeout of tour steps. Some
improvements regarding that will be made at [1] and probably by further
PR after that (improving the editor loading speed in general).
Meanwhile, this commit reviews the tour to not save the editor as it was
actually not needed in this tour (nothing has to be saved).
