Giftcards can be applied 2 times

[koljam]

mutation {
  result: applyGiftCardToOrder(code: "K3QJRL") {
    ... on Order {
      totalWithTaxAfterGiftCard
      giftCardsApplied {
        code
      }
    }
    ... on ErrorResult {
      errorCode
      message
    }
  }
}

When running this mutation 2 times, I get this result:

{
  "data": {
    "result": {
      "totalWithTaxAfterGiftCard": 397900,
      "giftCardsApplied": [
        {
          "code": "K3QJRL"
        },
        {
          "code": "K3QJRL"
        }
      ]
    }
  }
}

The total amount is reduced by 2x the giftcard value. Subsequent mutations don't add a 3rd giftcard.
When running removeGiftCardFromOrder, both giftcards get removed.

Expected behaviour

The giftcard schould only be appliable once.

Thanks for the report! This is fixed in v0.1.3 which was just published :)
