inferior: 'cached-channel-instance' does not cache unauthenticated instances. 

The comment saying that caching is fine even when AUTHENTICATE? is false
was true in commit 838ac881ec, but it
became incorrect in 7cfd789150, which
no longer calls 'latest-channel-instances' on cache hits.

* guix/inferior.scm (cached-channel-instance): Do not create CACHED when
AUTHENTICATE? is false.
