I'm hesitant to make so many code changes when there's another reported fix that is only a few lines of code.

Could you please test to see if 🐛 Batch finish Force Delete return always status message 0 files cleansed. Fixed

I am tested this issue (I used this module to delete orphaned files earlier) and i have a different perspective on this.
I am not able to reproduce the above stated issue on 2.0.x-dev@dev

Steps
----
1. Attached a new media/ image to a node.
2. Deleted the node, and image should appear in orphaned tab (BUG: its not appearing there)
2. Copy the fid from the list tab (/admin/config/content/fancy_file_delete/list)
3. Given it in the Manual tab (/admin/config/content/fancy_file_delete/manual) and given both fid's without ticking Force
4. File is geting deleted from the media and node with success message but living the traces in the media listing (/admin/content/media) see the screenshot (BUG: it should not leave traces in the media page).
