[fix] google-videos engine: ignore news articles

In the video search, google also sometimes includes news.  E.g. in the DE
language when you search for `!gov paris`, google adds an article from a german
newspaper (FAZ), I assume these are sponsored link (not tagged advertisement?)

Those links do not have an image / this patch ignores *video links* wqithout an
image ID.
