Update smoketest to account for backfills (#1882)

As I wrote in the commend:
We backfill island areas with data from the 2010 census, so if THOSE tracts
have data beyond the data source, that's to be expected and is fine to pass.
If some other state or territory does though, this should fail

This ends up being a nice way of documenting that behavior i guess!
