The Data Analytics folder is built in RimEclipseCase::defineUiTreeOrdering and
is hidden while the fault distance collection is empty. Adding the first result
only refreshed the view (or the collection itself), not the case, so the case
tree ordering was never re-run and the folder stayed hidden until an unrelated
event rebuilt the tree.
Refresh the owner case from the collection whenever items change, mirroring the
RimDataFilterCollection precedent. onItemsChanged adds the folder when the first
result appears, and onChildDeleted removes it when the last result is deleted.
Carries the "Fault Distance" rename through to the C++ class names, file
names, PDM/scriptable keywords and the Python API (add_fault_distance,
class FaultDistance). The RicNewFaultDistanceResultFeature command class
keeps its name.
