Announce mail seeded by app:test:seed-crypto-mail to JMAP clients (#344)

The command wrote the message and its thread without recording a JMAP
change, so no state token moved: an open EventSource got no StateChange
and Email/changes found nothing. On the phone that looked like an app
that does not notice new mail (karatektus/pl_mail_android#43).

It now records the delivery through MailChangeRecorder as ingest does:
the Email as created, its thread as touched, and an arrival in the Inbox.
