stripVendorExtensions recursion

[JProgrammer]

Hi with the new stripVendorExtensions on api docs the code does not take into account recursive structures which will result in an error

    at RegExp.[Symbol.match] (<anonymous>)
    at String.match (native)

Here is a minimal openapi spec to replicate the issue

swagger: '2.0'
info:
  title: Recursion
  version: 1.0.0
paths:
  /recursion:
    get:
      responses:
        '200':
          description: 200 OK
          schema:
            $ref: '#/definitions/Recursion'
definitions:
  Recursion:
    type: object
    properties:
      healthStatus:

tags: []

Hmm, that function should not be following references at all. Will double check.
