plugin XEP-0384, XEP-0391: download missing devices list:
when a peer jid was not in our roster, devices list was not retrieved, resulting in failed
en/decryption. This patch does check it and download missing devices list in necessary.
There is no subscription managed yet, so the list won't be updated in case of new devices,
this should be addressed at some point.
