KAFKA GH-223: Handle unexpected content type

Browse Source 
See https://github.com/spring-cloud/spring-cloud-stream-binder-kafka/issues/223

When using native encoding; NPE when no class name derived from the content type.

Do not attempt deserialization if `JavaClassMimeTypeUtils.classNameFromMimeType(contentType)`
returns `null`.

Test case in the Kafka binder.
