Show locale in region list even if suggested in language list

Even if English US is suggested, when choosing English I should
still see US in the country list.
Because now the same LocaleInfo object (from cache) can be present
in both lists (language & region), it means that the label should
depend on the context.
We also need to explicitely disable suggestions in the region list.
