[BUG] After uploading media from Google Drive, no thumbnail is created

[elynema]

Describe the bug
For videos uploaded from Google Drive via Dropbox (browse everything), no thumbnail is created once file conversion is complete.

For an example, see the last section (Cat in Slo Mo) on this media object: https://avalon-dev.dlib.indiana.edu/media_objects/g158bh28p

To Reproduce
Steps to reproduce the behavior, including the results:

1. Go to Any media object on avalon-dev
2. Edit -> Manage files. Add a new section from Dropbox, Google Drive
3. Once file processing is finished, click on the new section.
4. You will see the default video icon thumbnail, rather than a thumbnail from the content itself

Expected behavior
Expect a thumbnail to be created from several seconds into the recording, just like if a section file is uploaded from the web upload.

Environment (please complete the following information):

Additional notes

I wasn't able to find anything specific in the logs, but the Sidekiq dashboard has several ExtractStillJobs that failed with RuntimeError: Frame extraction failed. See log for details. from the last couple days. @cjcolvar Is there a separate log for background jobs? Since I didn't see anything about ExtractStillJobs or these failures in the regular log file, I'm worried that details aren't actually being logged.

My initial thought is that this may be another case of a method trying to pull the file from its original location on google drive, but the request is missing the auth headers.

May be resolved with #6129.

@masaball On avalon-dev the sidekiq log is in container-data/log/worker_startup.log. It would probably be good to rename that to something more obvious.
