Description of the Bug Report

#900 introduced validation ofincluded_resources but causes a regression that when one ofincluded_serializers of the current serializer of called view usesincluded_resources it will fail.

I assume validation ofincluded_resources should actually be done in the serializer meta class and only query parameters validated inIncludedResourcesValidationMixin.

See discussion#318 where there is also some code to reproduce it.
