Don't show duplicate Imms API vaccs records in activity log

Some Imms API records have a `discarded_at` date, because they were
deduplicated when they were ingested. These records should be
suppressed all over the UI; the user shouldn't know that they ever
existed.

This fixes the bug that these records were showing two cards in the
activity log:
- "Vaccinated"
- "Vaccination record archived"
