Bugfix: update layer names in layer list (when used in secondary fashion) on reload

1. The readers will overwrite the layer names if given in secondary fashion
   (additionally to layer/datatype)
2. The layer properties nodes will update the "real source" according to
   the actual name if the name is used in addition to layer/datatypes
