I change the URL of the third test case, because now the original URL
does not contain a video anymore, and there's no easy to get the real
URL from the /film/ one.
· Import from compat what comes from compat. Yes, some names are available in utils too, but that's an implementation detail.
· Use _match_id consistently whenever possible
· Fix some outdated tests
· Use consistent valid URL (always match the whole protocol, no ^ at start required)
· Use modern test definitions
