mod_s2s: Guard against missing 'to' on incoming stream Given an incoming <stream:stream from="example.com"> this line would have mistakenly reported the 'from' as the local host. Neither are technically required and may be missing, especially on connections used only for Dialback. Outgoing connections initiated by Prosody always have 'from_host' and 'to_host', so it is safer to check it this way.
