Videos instead of their thumbnails are downloaded.

Photos that list the value "Video Original" as an available size are threated as
videos. The download url of them has to be extracted from one the video sizes
(e.g. "Video Original", "HD MP4", "Mobile MP4", "Site MP4", etc.). Otherwise,
the video's thumbnail is fetched. Moreover, the file extension is adjusted to
"mp4".
