* If maxExposureDetectionsPerDay is 0, return a saner value than 99 days.
maxExposureDetectionsPerDay is checked separately and will abort the download task if necessary.

* When checking whether the last detection was recent, add a sanity check that causes it to not skip, if the last detection was in our future.

* Change primary key for risk result database to a monotonic ID.
This prevents time travel from breaking "get latest" as we will get the latest by monotonic ID, instead of "calculatedAt".

* We don't need `fallbackToDestructiveMigrationFrom(3)` until we actually upgrade the schema to 3.

* Fix database test (missing monotonicId)

* Catch exceptions during migrations and recreate the table.

* Add check for result size after recreating+insertion.
