Fresh installation of any packages dependent `openapi-client-axios` are broken

Hi @anttiviljami,

yesterday one of my experemental package was broken when was installed freshly (without package-lock.json and node_modules) with next error:

     TypeError: Cannot read property 'dereference' of undefined

      at crawl (node_modules/@apidevtools/json-schema-ref-parser/lib/dereference.js:44:15)
      at Object.dereference [as default] (node_modules/@apidevtools/json-schema-ref-parser/lib/dereference.js:19:22)
      at OpenAPIClientAxios.initSync (node_modules/openapi-client-axios/client.js:206:34)
      at Object.B.default (<index.js>:42:25)
      at new e.B (<index.js>:384:11)

After some drilling of some sources I detect that reasons of the problem is in:

json-schema-ref-parser library update from 9.0.6 to 9.0.7 release 9.0.7 "breakin" change (but not breakin by a docs)
openapi-client-axios incorrect incorrect usage of derefence from that library derefence has a second options param that type is $RefParserOptions and was never marked as optional
npm install that does not respect package-lock.json of dependencies https://github.com/npm/npm/issues/19458

So, that error can be catched by anyone who will install openapi-client-axios in new projects or while force deps upgrade, by that reason asking to fix it asap.
