Circular references in referenced OpenAPI broken: Error: Token "ChildObject" does not exist.

[daniel-sc]

Describe the bug

I get the following error on running ag asyncapi.yaml @asyncapi/html-template:

Something went wrong:
Error: Token "ChildObject" does not exist.
    at dereference (c:\devsbb\eaio-ng\nodejs\16\node_modules\@asyncapi\generator\node_modules\@asyncapi\parser\lib\parser.js:160:11)
    at handleCircularRefs (c:\devsbb\eaio-ng\nodejs\16\node_modules\@asyncapi\generator\node_modules\@asyncapi\parser\lib\parser.js:174:3)
    at parse (c:\devsbb\eaio-ng\nodejs\16\node_modules\@asyncapi\generator\node_modules\@asyncapi\parser\lib\parser.js:109:35)
    at Generator.generateFromString (c:\devsbb\eaio-ng\nodejs\16\node_modules\@asyncapi\generator\lib\generator.js:265:22)
    at c:\devsbb\eaio-ng\nodejs\16\node_modules\@asyncapi\generator\cli.js:154:9

Observation 1: When the circular refrence in ChildObject is removed, the generation works fine! Observation 2: When both schemas (ChildObject, ParentObject) are defined inside asyncapi.yaml everything works fine as well!

How to Reproduce

asyncapi.yaml:

asyncapi: 2.0.0
info:
  title: Account Service
  version: 1.0.0
  description: "This service is in charge of processing user signups :rocket:"
channels:
  user/parent:
    subscribe:
      message:
        payload:
          $ref: 'openapi.yaml#/components/schemas/ParentObject'
  user/child:
    subscribe:
      message:
        payload:
          $ref: 'openapi.yaml#/components/schemas/ChildObject'
components:
  schemas: {}

openapi.yaml:

openapi: 3.0.3
info:
  title: Title
  description: Title
  version: 1.0.0
servers:
  - url: 'https'
paths: { }
components:
  schemas:
    ParentObject:
      type: object
      properties:
        child:
          $ref: '#/components/schemas/ChildObject'
    ChildObject:
      type: object
      properties:
        sister:
          $ref: '#/components/schemas/ChildObject'

Expected behavior

Expect to generate successfully.
