Don't send XEP-0280 v1 copies back to sender 

An earlier version of XEP-0280 specified the <received/> and <sent/>
tags to be siblings of the <forwarded/> element, whereas the current
version mandates them to be parents of <forwarded/>.  The mod_carboncopy
module supports both variants.  However, the check that makes sure
clients won't receive a copy of the messages they sent didn't work for
the old-style schema.  This is now fixed.
