strange use of "statement" bot are resources, the first of type

the statements deleted and recreated are a faster way to access the
ordered relations than getting all relations with a source and sorting
them. if the orer of items change there was something strange before,
such a "strange" situation may happen when the relations have different
aging-values.

seems unncessary to me, you would have to iterate through resources of
type relation (listSubjectsWithProperty(RDF.type, KNOBOT.Relation),
check if the source matches and delete next/first if applicable.
