throw error if the videoID returned is different

Closes #3257

[Don't mind my previous (now deleted) comment]

We should probably put something in info["error"] instead of rising an exception. I'm pretty sure that rising an exception for the wrong video ID will break sonner or later.

Also, if we raise something, We should raise an InfoException (no trace) or just an Exception. A BrokenTubeException is used to give the name of a JSON object that we can't find.

EDIT: We can also create a dedicated VideoNotAvailableException

Then the user wouldn't have direct easy access to reporting the issue. Returning an info[error] means only a single message is displayed.

Ok for a VideoNotAvailableException.
