fix fdo#66586 Revert "fdo#46808, create IDL fortree::DefaultTreeDataModel"

This reverts commit fcd01fba.

Service DefaultTreeDataModel actually doens't exist ( and we can't find
when/where it used to :-( ) The treecontrolpeer.cxx change to
use the new service also had the undesired effect of throwing an exception
when the UnoTreeControl model is inserted ( previously this failed silently )
The net effect is the dialog control is malformed and not initialised
correctly
