Application duplicates attachment when submission is saved as a draft

[fourthletter]

Description

Application creates a different copy of the pdf every time the user saves a draft; the result is a duplicate attachment in the final submission.

The form validation code adds the 8-character suffix every time to the loaded attachment; see that the suffix chain keeps growing in length (but every time, it's a random token):

All those files are duplicated.
