ENH: Editor - Ensure a related merge volume is selected after a structure delete
Created by: rweiss42
After a structure delete (one or all), the slice viewers don't get their label layers updated with any sort of logic, they just select the "next" available label volume (determined I think by the order in which the label volumes were added to the scene).
Adding a call to select() in the delete methods should resolve this issue and will also make sure the Editor is in a good state following the removal of a node from the scene (which is probably a good thing to check for).
@pieper can you take a look?
