[FIX] website: adapt tests to new editor and new html editor

Scss tour was broken due to recent task that shows only 2 new custom scss
files if not in edit mode. As the tests was trying to read `website.ui.scss`
that is now in debug mode in a filter, it would not be found.

Html tour was broken due to new editor that changed the save process.
For some reason, after the drag & drop of a snippet, clicking fast on save
would not fire RPCs as it would not be considered as dirty.
(Editor would then close, you would still see the modifications even if nothing
was saved on DB)
