[Issue] Guard Magento_Catalog JavaScript from lack of minicart

Description

When the mini-cart is removed, or during the checkout, Magento_Catalog::js/product/storage/ids-storage-compare.js throws an error. The error is masked during checkout because there is a DOM element with id="checkout" which some browsers make available on window.checkout (so there's no error but the information assumed to be present isn't there).

This pull request changes the guard logic to protect against this error.

Edit: I found three more places where the lack of minicart causes errors. The minicart.js itself also suffers from this assumption, but I chose to not patch that here.
