[json] Outline View displays array of objects as duplicated keys of object

[nihonjinrxs]

Issue Type: Bug

Steps to replicate

1. Turn on outline view.
2. Create a simple JSON file as follows:

   {
   "MyArray": [
   {
     "name": "Object 1",
     "_id": 1,
     "data": [
       "a",
       "b",
       "c"
     ]
   },
   {
     "name": "Object 2",
     "_id": 2,
     "data": [
       "d",
       "e",
       "f"
     ]
   },
   {
     "name": "Object 3",
     "_id": 3,
     "data": [
       "g",
       "h",
       "i"
     ]
   }
   ],
   "OtherKey": "Some data",
   "ObjectKey": {
   "ObjectData1": "Data 1",
   "ObjectData2": 2
   }
   }

3. Look at the Outline View display, and notice how keys within the objects that are part of "MyArray" are included as object keys under the "MyArray" heading. These should instead be displayed as individual objects with keys of the array index, or similar.
