Apply gossiped encryption preference to new peerstates

Browse Source 
Encryption preference was already applied since commit 78d855c5ca,
but only for already existing peerstates.

As a result, new users ignored gossiped encryption preference in the
"member added" message and had to wait until someone gossiped encryption
preferences for inactive users the second time.
