Subject: [PATCH] Fix 'vsprintf(): Too few arguments' unexisting imported node
 exception

If the imported node does not exist, no arguments is  passed to BpConfig::addError() by ImportedNode::createFailedNode(). Added 'if' condition in BpConfig::addError() in case no arguments are passed to vsprintf.
