Combining JsonView with JsonUnwrapped

[mkoppanen]

Hey,

I ran into an issue when combining JsonView with JsonUnwrapped annotation. This could be potentially misuse of the API but seemingly the behaviour is unexpected.

The following test case demonstrates the issue, but the gist of it is that with json view IdType ends up as ObjectSchema, where as without it its correctly identified as IntegerSchema:
