Node tree updates can crash if the tree contains a node group that points at an "undefined" tree type.
This can happen if the tree is linked from a library and the path is lost,
or if a custom (python) tree is used and the script is not run.

The fix is to check if the node group type is valid ("registered") and return an empty list otherwise.
