Nested arrays aren't expanded

[zdne]

Given following blueprint:

# Resource [/r] 
## Retrieve [GET]

+ Response 200 (application/json)
    + attributes
        + a
        + b (array[X])


## Data Structures

### X
- c

The Retrieve response JSON is never expanded.

This is an issue with boutique. Need more digging to check if there are other similar test cases.
