fix: a loop through the site's absolute URL lists each address once

The loop and chain path of a redirect notice appended the final target
when it was an absolute URL of the site itself, so a loop read
"/a → /b → /a → https://example.test/a". The site URL now counts as
internal, as it does when the chain is followed.
