verify: use similar language for missing manifest and file revisions

When a changeset refers to a manifest revision that's not found in the
manifest log, we say "changeset refers to missing revision X", but
when a manifest refers to file revision that's not found in the
filelog, we say "X in manifests not found". The language used for
missing manifest revisions seems clearer, so let's use that for
missing filelog revisions too.
