mod_s2s: Don't bounce queued error stanzas (thanks Martin)
The check for the type attr was lost in 11765f0605ec leading to attempts
to create error replies for error stanzas, which util.stanza rejects.
Tested by sending
<message to="reject.badxmpp.eu" type="error"><error/></message>
which produced a traceback previously.
