configure products before price update

closes #4053

Short Description and Why It's Useful

There are no prices because render-list doesn't have configurable_children data. So we clear prices for children (clearPricesBeforePlatformSync), then we fetch render-list, update prices for parent and at the end we return child (variant) as product. So child has price:null.

I've checked magento docs and probably there is no option to add configurable_children to render-list data.

So only solution is to add children skus to parent skus. But we can't fetch all of them because we will have to fetch 500+ skus :/

We can change order in processCategoryProducts, so in that case parent will be replaced already by child (variant), but it's probably huge change. This require some tests and comments.
