plugin XEP-0373: download public keys if they are not found in local storage:
public keys were only obtained from PEP notifications, however this wasn't working if the
entity was not in our roster.
Now if no public key is retrieved from local storage, the public key node is requested,
and an error is raised if nothing is found. This allows the use of OX with entities which
are not in roster.
