improve derivatelink migration commmands and label handling

Description

We want to add the following changes

  • list mycore objects for migration via java (if the SOLR index is corrupt).

  • migrate derivate label to classification (if it looks like an identifier)

  • migrate service flag to title (if it is a professorenkatalog object)

  • allow null value for mycorederivate/@label (now deprecated)
