[FIX] website: restore snippet animation API

Before the website refactoring, snippet animations were cleaned thanks
to the `stop` method. As those animations are now extensions of the
standard `Widget` class, the `stop` method was replaced by the standard
`destroy` method. This was tweaked so that the $el is not removed from
the DOM, but with proper cleaning of events. However, this changed the
way the `stop` method content has to be called. Indeed, we should be
allowed to call the `_super` method and then use the $el variable.
