FIX: AtomIdDescriptor was not using internal_iterator but full ObservedIterator.

  • this causes messy update()-cascades because on destruction of the iterator during the find, which is e.g. used by AtomIdSet::const_iterator(!), an Observer signal was triggered.
  • NOTE: In Descriptors we may _always_ use internal iterators, as this never does any harm to the World with respect to insertion/removal of atoms or molecules.
  • this [closed #182].
  • Property mode set to 100644
