Returns error in case api response contains 'errors' key

[FranceBe]

Widget is based on POST v2/payments/eligibility response to define its behavior.
Most of the time, eligibility response in case of error is constructed with a property error_code.
In the widget code, we explicitly covered this case with

  if ('error_code' in res) {
       setStatus(statusResponse.FAILED)
  } else {
  ...

But there is a specific scenario in which the API respond with a error that does not contains error_code, so
it was not correctly catched in the widgets's code, and so the widget was blocked in "PENDING" state

This behavior can be reproduced locally by configuring the widget this way in basic.html (from the master branch) :

function renderPaymentPlans() {
  var purchaseAmount = 0
  widgets.add(Alma.Widgets.PaymentPlans, {
    container: '#alma-widget-payment-plans',
    locale: 'fr',
    purchaseAmount,
    plans: [{
      installmentsCount: 1,
      deferredDays: 0,
      deferredMonths: 0
    }, {
      installmentsCount: 2,
      deferredDays: 0,
      deferredMonths: 0
    }]
  })
}

Which corresponds to calling POST v2/payments/eligibility with the payload :

{
    "purchase_amount": 0,
    "queries": [
        {
            "installments_count": 1,
            "deferred_days": 0,
            "deferred_months": 0
        },
        {
            "installments_count": 2,
            "deferred_days": 0,
            "deferred_months": 0
        }
    ],
    "billing_address": null,
    "shipping_address": null
}

Then, you'll notice the API response is :

{
    "errors": {
        "running": {
            "message": "'purchase_amount'"
        }
    }
}

Now, this PR fixes this behavior by adding a condition to the previous one :

if ('error_code' in res || 'errors' in res) {
  setStatus(statusResponse.FAILED)
   } else {
   ....

And now, the widget is correctly hidden because of the eligibility error
