add ability to cancel a payment intent

[OMFG5716]

Added additional condition in the patch method of the PaymentIntent service. It checks for a key "cancel" that is passed to the data arg.

Now, one can cancel a payment intent by doing so:

feathers.service('stripe/payment-intent').patch(id, { cancel: true });

Thanks for the PR! This looks good and I will try to get this deployed later today.

Sorry @OMFG5716 , on second look cancel is undefined.

You need to define the cancel var. This should be done like

const { capture, cancel, ...rest } = data;

on line

feathers-stripe/lib/services/payment-intent.js

Line 24 in 5739fc3

const { capture, ...rest } = data;

Also, please remove the returns between the if blocks for consistency.

It should look like

_patch (id, data, params) {
  const { stripe } = this.filterParams(params);
  const { capture, cancel, ...rest } = data;
  if (capture) {
    return this.stripe.paymentIntents.capture(id, stripe);
  }
  if (cancel) {
    return this.stripe.paymentIntents.cancel(id, stripe);
  }
  return this._update(id, rest, params);
}

Ok Gotcha, I think apart from canceling I've missed one more status update for a PaymentIntent. I'll try and add that too and make sure that's destructured like above. I'll push shortly.

Above fixes pushed! I meant, just like canceling, adding the ability to confirm a PaymentIntent, but I'll open a different PR for that I guess.

Thanks! Yea, another PR would be best because this repo automatically generates a CHANGELOG from PR's so that way it will be reflected there.
I will wait for the second PR before merging and publishing to NPM.

Thanks again!
