Before this commit, the tours default_shape_gets_palette_colors and
edit_link_popover were not using the tour utils function
registerEditionTour, that starts a tour on the iframe, in edit mode,
with a timeout on the first step.
Because this timeout was not there, loading the iframe and the snippets
menu could take longer than the default timeout and the test would fail
inconsistently.
