Contact email: a report's rev is its own change; another address starts fresh

- from_report applies its change and reads the id and rev together, so a
  removal made while that change is sending is newer than the report; the
  report's redaction window now starts before the address is saved.
- A report with a different address replaces the saved one with follow-up
  questions only: update notices aren't carried over to an address nobody
  agreed them for, and the form says so before sending.
- Settings refreshes after every report send, whatever the box shows by then.
- privacy.md: a report with follow-up ticked also saves and sends the address.
