Add video ID to ERROR log

[LaazV]

I sometimes get errors stating that the video is not available in my country, it would be useful to print the video ID with the error, so that we can just copy the ID and download using a VPN. Since it just writes ERROR: + error_message we have to set debug flag as true and wait it out until we reach the same error and find the ID from there..

I'm going to try to make a PR this weekend on this. Is it ok?
