Steps to reproduce:

1. Configure Elasticsearch
2. Make sure ibexa.commerce.site_access.config.core.default.enable_bestsellers is set to true in silver.eshop.yml (which it should be, by default)
3. Create a product and purchase it at least twice
4. Access the /bestseller route

No bestsellers are displayed.

Additionally, it is impossible to configure a Bestsellers block for the Landing Page, because it requires providing a product category, which doesn't exist in the new catalog (see screenshot).

Note: in previous versions bestsellers did not work with LSE, but worked with Elastic or Solr. Tested with Elastic only.
