GestaltOrAnonSerializer: prepare input data for 'run_validators'

The "run_validators" method of rest_framework.serializers.Serializer
seems to expect a dict. Thus deserialization ("to_internal_value")
fails, since it returns a proper "Gestalt" instance (which cannot be
handled by "run_validators").
