JSON Views: Resource model serializer does not support @JsonUnwrapped

[olaf-otto]

The introduction of JSON views in 5.1.0 features a custom JSON serializer implementing the automated addition of additional JSON attributes such as :type. This custom serializer is missing support for @JsonUnwrapped (see https://fasterxml.github.io/jackson-annotations/javadoc/2.0.0/com/fasterxml/jackson/annotation/JsonUnwrapped.html). This support is specific to the BeanSerializer and should be added.
