When running the D8 upgrade in a language other than English, the locale system is used, which includes locale string tables. So we need to move corresponding updates to locale.inc (update_prepare_d8_language)
Actually, this was causing a lot of issues with this patch, which atm needs some hacking around locale queries for the update process not to crash
(Which means if we fix this one, that queries could be simplified.)
This is a very small and straight forward patch, most of the lines are renumbering the other locale updates.
