[la7] Fix extraction (closes #23323)

Browse source 
Parsing `videoParams' or `videoLa7' JavaScript snippets as JSON is getting too
hard for js_to_json.  Just extract the `vid' from there and use _search_og_*
for all other data.

Remove the 2nd test: unfortunately the page are removed after a couple of
days/weeks.

Thanks to Elia Geretto for spotting and suggesting several problems with the
tests!

Closes #23323.
