Do not use OAuth token for video-by-id queries

They started to fail with '401: authentication failed'.

It seems that these requests do not require authentication, according to
twitch API documentation:
https://dev.twitch.tv/docs/v5/reference/videos/#get-video
"""
Get Video
Gets a specified video object.

Authentication
None

URL
GET https://api.twitch.tv/kraken/videos/<video ID>

Optional Query String Parameters
None
