Aggiornare 'dhp-workflows/dhp-doiboost/src/main/java/eu/dnetlib/doiboost/orcid/SparkConvertORCIDToOAF.scala'

The change is to fix the issue that arises when the same work appears more than once on the same ORCID profile. The change avoid to replicate the association doi -> author when the orcid id is already associated to the doi.
