PersistentEntityToJsonSchemaConverter does not honor @Description annotation [DATAREST-679]

Ryon Day opened DATAREST-679 and commented

I was puzzled to discover that in my project, annotating fields within domain objects with the @Description annotation did not result in a corresponding description element within the JSON schema.

I ran through the code in the IntelliJ debugger and found that the "fallback" property of AnnotationBasedResourceDescription overrides the actual message in the same class. If SDR cannot find a message with the key rest.description.$type.$field it will return null.

This seems to be the opposite of the desired behavior; it should use the explicitly stated value of the description annotation's value, then look for the fallback, then return null.

Affects: 2.3.2 (Fowler SR2), 2.4 GA (Gosling)
