If the url doesn’t specify the protocol we can’t directly use it to download the webpage, we would need to build a new url.
Instead, we let the generic extractor add the protocol.
More age limit of videos for adult-related sites.
Note that, for redtube, I explicitly left the variable containing the age
limit, since the comment justifying the age limit is a good thing to have.
That being said, I included the age limit field on the test, to better
reflect what the information extractor does (even if it may not break the
automated tests).
