mod_authz_delegate: make resistant against startup order issues There is no guarantee that the target_host gets activated and initialized before the host this module is loaded on. As add_default_permission is called during load time by many modules, we need to be prepared to queue stuff.

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.
