Bug fix: preventing NPE when party is null, it means it has no groups
FenixAPI /person/evaluations returns all evaluations, even when enrolment period is not defined.
FenixAPI /degrees returns degree's name according to ?lang param
FenixAPI /contacts added.
FenixAPI /degrees degree's name uses getNameI18N(executionYear) instead of getNameI18N()
