[OpenApi] Infinite recursion

[coyotte508]

Describe the bug

The openapi handler triggers a "Maximum calls stack size exceeded" error

To Reproduce
Steps to reproduce the behavior:

Use the following openapi file (I trimmed down as much as possible while keeping the error):

openapi: 3.0.0
info:
  title: 'hello'
  version: '0.1.0'
  contact: {}
tags: []

Expected behavior

No infinite recursion

Environment:

• OS: WSL2
• @graphql-mesh/openapi: 0.13.2
• NodeJS: 14.15.5

I added test for this swagger document;
54f87a6
And it works as expected with the new OpenAPI handler, we are working on.
We are planning to drop the existing openapi handler in favor of new newOpenapi handler, you can check the configuration schema to see how to use it.
Thanks for creating this issue and sorry for the late response.
