[FIX] web_editor: remove useless test-breaking warning

A console.warn instruction was added with [1] in case an user interacts
with an editor widget which does not declare any linked option method
(as it is most probably a dev mistake). We have cases where it makes
sense though, adding a custom button with more complex events and
interactions or simply in some strange custo. This warning prevents to
test those uncommon behaviors in a tour test (which is what following
commits of this PR are trying to do).

This commit simply removes the warning.
