Check if another file has been uploaded with the same blake2 digest

[alanbato]

This tries to resolve #2490

I'm not sure if the uniqueness of the blake2 digest should be validated on file uploading or before, or if hijacking on the same "File already exists" message is helpful enough.

Also, I'm getting a weird error on my test, making it fail. Something about the request object missing a 'user' attribute.

Thanks for your feedback y'all.

The error is because your test is getting to this line:

            request.db.add(
                JournalEntry(
                    name=release.project.name,
                    version=release.version,
                    action="add {python_version} file {filename}".format(
                        python_version=file_.python_version,
                        filename=file_.filename,
                    ),
>                   submitted_by=request.user,
                    submitted_from=request.remote_addr,
                ),
            )

Which means it's trying to add the file being uploaded, so it seems like either something is wrong with your test, or with the new logic you added.
