Fixed member.deleted webhook having an empty payload

no issue

- the members output serializer was passing model objects through on `frame.response` but the webhooks serializer doesn't know how to deal with those
- adjusting the output serializer to use a mapper as per the other serializers means that POJOs are being passed through which allows the webhook serializer to correctly pick out the changed attributes
