Undo too-aggressive code collapsing from tree mode refactoring

While abstracting processes from row display, code relating to
row parent sorting was moved to row-level that in fact must be
done at process-level (using the Row_compareByParent_Base call
circumvented this unintentially).

Resolves #1378
