White Noise can find a coinos account: relay lists go to its directory relays

The Android app said a coinos user "isn't on White Noise yet" although
their KeyPackage was published: MDK will not invite an account whose
kind 10002 and 10050 lists it cannot find, and it looks on
relay.eu/us.whitenoise.chat and purplepag.es, where coinos never wrote.
The client now passes the account's already-signed lists along to those
relays (no signer needed, nothing rewritten), weekly and until both exist.
