Carrierwave leaves behind empty directories

[whereismyjetpack]

When performing a restore this morning, I noticed a bunch of empty directories in the uploads directory. This is due to carrierwave not removing the directory of a file when the file is removed. This seems to be a long standing issue, that can be resolved with an after_action. I like the solution proposed here

If we think this is sane work to do, I can get started on it

Yeah, this looks like the sanctioned way to do it.

I'd say go ahead 👍

This is fixed for Activity Insight OA Files: https://github.com/psu-libraries/researcher-metadata/blob/main/app/uploaders/activity_insight_file_uploader.rb#L5

It still needs to be done for ScholarSphere files (from the standard OA workflow): https://github.com/psu-libraries/researcher-metadata/blob/main/app/uploaders/scholarsphere_file_uploader.rb#L4
