mod_smacks: also count outgoing MAM messages
mod_smacks doesn't count outgoing MAM messages, which causes warnings in Prosody such as:
> The client says it handled 41 new stanzas, but we only sent 2
It seems mod_smacks is in the wrong here and that it's too strict in trying to determine what is a valid stanza to count.
In RFC6120:
> Definition of XML Stanza: An XML stanza is the basic unit of meaning
> in XMPP. A stanza is a first-level element (at depth=1 of the stream)
> whose element name is "message", "presence", or "iq" and whose
> qualifying namespace is 'jabber:client' or 'jabber:server'.
