After enabling options.EnableResourceHooks = true; I get a NullReference on GET Articles/GetSecondary [id/relationshipName]

See original GitHub issue

DESCRIPTION

The request is crashing on this line because the type is IIdentifiable instead of the implemented type Image. https://github.com/json-api-dotnet/JsonApiDotNetCore/blob/master/src/JsonApiDotNetCore/Configuration/ResourceGraph.cs#L85

The implementation seems to be lost at this place: https://github.com/json-api-dotnet/JsonApiDotNetCore/blob/master/src/JsonApiDotNetCore/Hooks/Internal/ResourceHookExecutorFacade.cs#L131
