[pubsub] FormNode(Provider) should not fail if there is no DataForm

Browse source 
Error IQ respones may not contain a data form, e.g.

<iq type="error" id="6LXNC-48" from="pubsub.openfire.xmpp.test" to="anno@openfire.xmpp.test/5dsi4g084a">
  <pubsub xmlns="http://jabber.org/protocol/pubsub#owner">
    <configure node="fdp/submitted/spot_report"/>
  </pubsub>
  <error code="403" type="auth">
    <forbidden xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>
  </error>
</iq>

Also FormNode's toXML() already handled the case where submitForm was
'null'. Only the constructor threw a IAE if submitForm was 'null'.

Fixes SMACK-910.

Closes: https://github.com/igniterealtime/Smack/pull/471
