Use file attachments override for the user file attachments resource.
Review Request #8822 — Created March 17, 2017 and submitted — Latest diff uploaded
FileAttachmentListResourcehas a helper that makes it very
easy to upload files using the Python API. This override was used for the main
file attachments list endpoint, but wasn't for the user file attachments list.
This change updates it to use that helper for both.
