channels: 'authenticate-channel' doesn't check relation with intro commit.

Fixes <https://bugs.gnu.org/41908>.
Reported by Jan Nieuwenhuizen <janneke@gnu.org>.

The relation check imposed an extra restriction that was unnecessary:
it's enough to authenticate the set difference between the closure of
START-COMMIT and that of END-COMMIT.  Any attempt to jump to an
unrelated commit would lead to the authentication failure of one commit
on the way.

* guix/channels.scm (authenticate-channel): Remove extra
'commit-relation' check when (null? commits).
