Prober: an inspection per candidate; no inner name that is the release's name

A release can have several candidates of a kind (two RAR sets): keyed by
(release, kind) both landed in one upsert ("ON CONFLICT DO UPDATE
command cannot affect row a second time"), and the batch was lost.
release_inspections is keyed by candidate now; the first run's results
are cleared and probed again. A random-named file's yEnc name is often
its random name: an inner name equal to the release's name is dropped.
