Drop System#track_parents DSL function

No external user needs to manipulate the actual object dependency
graphs. This was maybe introduced for debugging purposes at that time
but if someone messes with this in prod - good luck with that. Oh, apart
from that it's broken :( and doesn't track parents as its implies but
children.
