element.py: Only store the direct reverse dependencies on an element.tristan/bschubert-pipeline

Ensures that `Element.__update_state_recursively()` works as intended
and only updates the states on reverse dependencies when a source cache
key has changed, stop descending into reverse dependencies as soon as
a cache key is unchanged.
