fix: check purgatory in maintainer announcement lookup

is_maintainer_in_any_announcement only queried the database, missing
announcements still in purgatory. A maintainer's announcement (which
lists the recursive maintainer) may arrive and enter purgatory before
the recursive maintainer's announcement does, causing the maintainer
exception check to return false and reject the recursive maintainer's
announcement.
