mod_presence: Send unavailable presence in current thread run `session:dispatch_stanza(pres)` enqueues processing of the stanza in the sessions async thread, but becasue the entire stream close handling is now in that thread it would process the presence after the stream and session was completely closed, leading to weird errors "sent to a resting session". We call core_process_stanza() since this is what :dispatch_stanza calls in the end.

Structure of a session:


session {
	-- properties --
	conn -- the tcp connection
	notopen -- true if stream has not been initiated, removed after receiving <stream:steam>
	type -- the connection type. Valid values include:
			-- "c2s_unauthed" - connection has not been authenticated yet
			-- "c2s" - from a local client to the server
	username -- the node part of the client's jid (not defined before auth)
	host -- the host part of the client's jid (not defined before stream initiation)
	resource -- the resource part of the client's full jid (not defined before resource binding)
	full_jid -- convenience for the above 3 as string in username@host/resource form (not defined before resource binding)
	priority -- the resource priority, default: 0
	presence -- the last non-directed presence with no type attribute. initially nil. reset to nil on unavailable presence.
	interested -- true if the resource requested the roster. Interested resources receive roster updates. Initially nil.
	roster -- the user's roster. Loaded as soon as the resource is bound (session becomes a connected resource).
	
	-- methods --
	send(x) -- converts x to a string, and writes it to the connection
	close(x) -- Disconnect the user and clean up the session, best call sessionmanager.destroy_session() instead of this in most cases
}

if session.full_jid (also session.roster and session.resource) then this is a "connected resource"
if session.presence then this is an "available resource" (all available resources are connected resources)
if session.interested then this is an "interested resource" (all interested resources are connected resources)
