When an user saves its website, all the animations are destroyed so that
a clean DOM is saved. This is particularly important for snippets like
the latest post one that would crash the page if not cleaned before
saving.
Two cases were found where animations were not cleaned before saving and
this is what this commit fixes:
- When an user used the undo/redo system, all animations were lost as
the DOM is recreated.
- When an user duplicated a snippet, animations were not restarted on
the cloned element.
