mod_rest: Include full_jid property on origin Fixes permission check in disco#info query to your own account, where the 'to' would have been stripped since it equals the account JID, leaving mod_disco passing nil, which triggers an error in module:may()

This module discards typing notifications sent to a bare host JID,
preventing error replies to be sent. These errors are harmless but can
be annoying sometimes if your client shows them prominently.
