[DEV-13912] update download response to be sorted

[loreleitrimberger]

Description:

The json saved in the download job isn't sorted causing the download_types to be sorted differently

Technical Details:

I changed the way I went about sorting this. The only columns that need to be unsorted are the columns so this gets the columns if they exist and after sorting the json_request re-adds the columns in their original order

1. N/A Unit & integration tests updated
