mod_ping: Fix double response to internal ping When responding to a ping from elsewhere in the same Prosody the send function will be host_send from core.hostmanager, which does not return anything. Tailcalling it therefore lets the iq event fall trough to handle_unhandled_stanza in core.stanza_router, which responds with an error. This error also goes into handle_unhandled_stanza which discards it. Noticed because I have a module that points out when a stanza error reply is created without a text argument.
