Fix status check not rendering before 5.19 migrations

This fixes an issue where the status check page does not render when
migrations to 5.19 are pending because the is_active column hasn't been
added yet.

The rationale for this change is to avoid scenarios where users forget
to run upgrades because there's no status check warning.
