[JDEV] Chatting with the correct resource

[Joe Hildebrand]

This is one of those things that is a little counter-intuitive.  The
language that's in the spec is correct, particularly when combined with the
rule that if a message is sent to a non-existent resource, it gets delivered
as if it has no resource.

There have been clients in the past that always sent to the user at host jid
(which is what you are suggesting), and user-experience-wise, they aren't
great, since some of the messages in a conversation end up going to the two
different resources, as auto-away priority changes happen.

The rules that are in the spec are our based on our best practices based on
real use patterns that we've seen.
