When adding 3 labels at once, 3 identical deck cards are created #11

I suspect gitea is sending multiple webhooks when batch-adding labels to an issue. This causes node to almost-simultaneously add the deck cards. Because of this, the exist check fails for all 3 cards, and all 3 cards are created.

Temporary workaround; don't add Deck and another label in the same operation. Add deck, let it save, then add all the labels you'd like.
