[IMP] website: add tests for all snippets (drag and drop)

Image gallery snippet when dropped is throwing a traceback.
This lead to the editor not usable anymore, as any JS error will prevent any
further action (no JS will work anymore).

This introduce a test that will drag and drop every snippet in a page and click
on it to load its settings in the right panel.

Note that it will remove the snippet before drag & dropping the next one, as
having too many snippet will impact the perf, even killing the browser entirely
if there is a lot.
