On clean and existing installs, the default product created should be named the same as the site title in the first setup so the UX on Portal and everywhere is consistent. This change adds a migration to update existing sites which already have a default product created via fixture, and rename them to their current site title. The rename is only done if the Product name is still the same as in fixture - `Default Product`.
