Array type of RAML union being displayed incorrectly

[deiteris]

There are three cases, when an array type of RAML union is displayed incorrectly:

1. Should display Array of: containing just a string type (see how StringArray is displayed), but just string type is displayed.

#%RAML 1.0
title: Test API

types:
  StringArray:
    type: string[]
  UnionArray:
    type: StringArray | string

1. Same as above, except it additionally shows items like it's an object property.

#%RAML 1.0
title: Test API

types:
  StringArray:
    type: array
    items: string
  UnionArray:
    type: StringArray | string

1. Should be displayed as Array of: listing object properties (see how ArrayType is displayed), but displays just object properties like it's an object.

#%RAML 1.0
title: Test API

types:
  ArrayType:
    type: array
    items:
      type: object
      properties:
        test: string
  UnionArray:
    type: ArrayType | string

Apparently, this.hasParentType check is missing for them for some reason. I might look into it.
