Xid created for JTS imported transaction set up wrong node name

For JTS being able to handle multiple inflow transactions there was made fix at https://issues.jboss.org/browse/JBTM-2893. Unfortunately the fix introduces issue where node name of the newly created Xid is incorrect. Even we have imported transaction which should be considered as subordinate we set up automatically node name equal to the current Narayana node.

I expect, the correct behavior should be to let the node name being the same as it was provided by import transaction call.
