Follow-up to #3287, #7867
We should test that the collator loads data conforming to the parentLocales.json. Currently we have a test that alerts us when parentLocales.json changes, but we don't actually test the behavior plumbed through the Collator constructor.
We can use Collator::try_new_unstable with the SourceProvider instrumented to track which data loads succeeded.
