Make sure Jackson annotations are taking into account in schema generation

[stuartwdouglas]

e.g. if a field is renamed via Jackson annotations this should be picked up in schema extraction

[tomdaffurn]

So with this class, the schema should have a FirstName field, not a first field:

public class Person {
    @JsonProperty("FirstName")
    private String first;
}

Yes, that is correct
