* Do not try to get child nodes from NodeManager if self is transient

Browse source 
* Throw an exception when trying to get a group-subnode from a
   transient node (it doesn't work, so better be clear about it)
* Do not set "name" property in groupby nodes, just stick with "groupname"
* Always set node properties in propMap if self is transient
