readonly is ignored for array property in model.

If a model has a readOnly array property, readOnly field is ignored and set to null when parsed with swagger parser.

Consider definition shown below.

  Category:
    type: object
    properties:
      id:
        type: integer
        format: int64
      users:
        type: array
        items:
          $ref: '#/definitions/User'
        readOnly: true
    xml:
      name: Category

Property "users" is an array of type "User" which is readOnly.
Swagger parser ignores readOnly and when parsed, readOnly is set to null.

Swagger swagger = new SwaggerParser().read("test.yaml");

test.txt

Start at SwaggerParser().read("test.yaml") and use the supplied test.txt definition to trace how the readOnly array property is parsed. Done means the users property retains readOnly: true instead of becoming null when the model is read.
