Subject: [PATCH] test(domain): a document-wait timeout expires the
 registration to Verlopen (refs #102)

RED: Registration.Expire() moves an open registration to a new terminal
Verlopen status, needs no zaak, is idempotent on redelivery, and is rejected
once the registration has been decided or withdrawn.
