Demo version on vercel doesn't 'always' update cart

[psntr]

Strange enough, if you open your browser in private mode and add the first product "Quarter Zip" to your cart and then within the cart side modal, the buttons (remove / or add more item) don't work. It send requests but do not update the cart value.

For those who experienced similar issue, I found a quick fix:

Add this line:
cartId = JSON.parse(localStorage.getItem('cartId'));
in src/routes/+layout.svelte after
await callCreateCart(); in line 27.

Explanation, on first load, there is no cartId, so the variable cartId is null:

if (cartId === 'undefined' || cartId === null || cartIdExpired) {
        await callCreateCart();
}

The await callCreateCart(); creates a new cartId but do not re-assign it to the variable cartId after it's been created therefore the cart didn't update because we sent a null value but once we re-assign it right after the await callCreateCart(), the cart responds correctly.

Hope you guys can add this @leerob / @StephDietz / @dominikg
