Error in testing when updating arguments passed to stripe components

Even though we have turned the `mock` config option on during testing, we still get an error about a missing method, `update`, when running our test suite:

> Uncaught TypeError: `Ember.get(...).update` is not a function

It's pointing to here:

https://github.com/code-corps/ember-stripe-elements/blob/74540fc5ed106b86916eef2c29059e231095903d/addon/components/stripe-element.js#L54-L57

I'm guessing this is just because that method isn't mocked in your `StripeMock` class and that's merely because you don't have any tests that try to update the attributes after rendering. Replacing your mock with our own copy which also mocks the `update` function makes our tests pass again.

Commencez par addon/components/stripe-element.js aux lignes 54-57, puis examinez la classe StripeMock et exécutez la suite de tests pour reproduire la méthode update manquante. Ajoutez une couverture de test pour la mise à jour des arguments du composant après le rendu, et considérez l’issue comme terminée lorsque le mock prend en charge cet appel et que les tests passent sans TypeError.
