Renamed Stripe Products from "Default Product"

refs TryGhost/Product#1289

Due to a bug in site setup some Tiers were named "Default Product" and
so the corresponding Stripe Product was also named this. This adds a
Stripe migration to rename any Stripe Products from "Default Product" to
the site title.
