• Ticket: https://openscience.atlassian.net/browse/ENG-12605
• Feature flag: n/a

Purpose

Users couldn't submit a registration created from scratch when files were attached. Deleting a file from the file list only removed it from the question on the current page. If the same file was attached on another page, that answer kept pointing to the deleted file and submit failed with "All files attached to this form must be registered...". Re-uploading didn't help because the old file still showed up there with the same name.

Summary of Changes

1. Deleting a file now removes it from every file question in the draft, not only the one on the current page.
2. Newly attached files are stored in the same shape as saved ones, so the duplicate check and removal work right after attaching.
3. Updated unit tests.

Side Effects

Deleting a file can now also update file answers on other pages of the draft.

QA Notes

1. Create a new registration with no project, using a template that has file questions on more than one page (e.g. Generalized Systematic Review).
2. Attach the same file on two pages.
3. On one of the pages delete the file from the list and upload it again.
4. Go back to the other page, the deleted file should no longer be attached there.
5. Attach the files you need and submit, it should go through without the files error.
