the class NodeLabelsFieldTest method shouldHandleRandomAddsAndRemoves.

/*
     * There was this issue that DynamicNodeLabels#add would consider even unused dynamic records when
     * reading existing label ids before making the change. Previously this would create a duplicate
     * last label id (the one formerly being in the second record).

     * unforeseen issues as well.
