fix(product): fix product variant update price with min_quantity and max_quantity

[BeyondOT]

What :

The issue is updating the variant price with min_quantity and max_quantity always returned null for both these attributes. Which is not the expected behaviour based on the admin api reference. https://docs.medusajs.com/api/admin#products_postproductsproductvariantsvariant

How :

Make sure to include all the attributes when updating the variant price.

Testing:

Update variant price through api including min_quantity and max_quantity.

I just added a commit that fixes the unit test error.

The price update fix was made by spreading the price object in money amount so the test should expect the currency code to be there as well if it was included in the price object.
