ID Verifier: Update requests for records which have not been accepted.

If the user resubmits an ID verification request, this request will
overwrite the other one unless the ID has already been accepted. If the
ID has been accepted, simply return the result. For now we do not allow
ID reverification.
Voting Booth: Resubmit verification request when user revisits
verification page

Generally speaking the user won't need to go back to the verification
page unless something is wrong, so we'll go ahead and resubmit his
verification request when he visits this page.
