Drafter aborts while rendering JSON value for a non-object inside an array of objects

[kylef]

The included API Blueprint caused the assertion at

drafter/src/refract/JsonValue.cc

Line 95 in bb00117

assert(false);

to be hit:

$ ./bin/drafter <document>
Assertion failed: (false), function renderProperty, file ../src/refract/JsonValue.cc, line 95.
fish: './bin/drafter <document>' terminated by signal SIGABRT (Abort)

## GET /

+ Response 200 (application/json)
    + Attributes (array[object])
        + Thing

Drafter 4.0.0-pre.3

Drafter 3.2.7 succeeds and returns the following JSON body:

[
  {
    "": "Thing"
  }
]

It does not produce any warnings or errors.

Another case, perhaps not same bug but it seems related:

# GET /

+ Response 200 (application/json)
    + Attributes (Array)
        + (object)

## Data Structures

### Array (array)

Assertion failed: (hasValue_), function get, file ../src/refract/Element.h, line 75.
fish: './bin/drafter 682-1.apib' terminated by signal SIGABRT (Abort)

It's independent. See #683
