Temporarily disable saving clean tags to disk

[obulat]

Fixes

Fixes #2556 by @obulat

Description

This PR adds a check for the field when saving the cleaned up data. We skip tags so that the disk space is not filled up during the data refresh. The tags are still cleaned before saving them to the database.

Testing Instructions

I used the csv data from the gist in this PR description: from #904 . The sample data loading has been updated to check for document count in the index, and to test locally I disabled those checks (because there are only 1900 images in that gist).
When I ran just init, I saw the files in the /ingestion_server folder, without tags.csv.
