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.
