Fix NPE caused by missing ApplicationEventPublisher in AnswerRepository
The CouchDbAnswerRepository
already used its own
ApplicationEventPublished
and unintentionally overrode the
setApplicationEventPublisher
of the abstract repository class. The
publisher was no longer used anyways, so it has been removed.
Furthermore, the ApplicationEventPublisher
is now visible for child
classes.
