Cannot read property "token" of undefined

[jvgeee]

Using the sample code in the readme to fetch a form, I'm getting:

(node:23596) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'token' of undefined
    at Form._fetchResponses (~/node_modules/@lirantal/typeform-client/src/Form/Form.js:95:31)
    at processTicksAndRejections (internal/process/task_queues.js:97:5)
    at async Form.fetchFormResponses ~/node_modules/@lirantal/typeform-client/src/Form/Form.js:118:51)
    at async ~/test.js:16:14

The error comes from this line in the node module:

      if (apiResult.page_count === 1) {
        break
      } else {
        const len = apiResult.items.length
        const lastItem = apiResult.items[len - 1]
        tokenValue = lastItem.token
      }

Might need a more defensive fix?

For reference, my form has 6 questions and no responses.

Hey @jascination, thanks for raising an issue.
Indeed looks like there's simply no more data to fetch and hence no token exists.

Would you want to submit a PR that fixes the issue? I'm happy to merge it.
