"All done" output even when using --quiet

[kkmuffme]

wp import foo.xml --authors=create --quiet

Outputs:

<p>All done. <a href="https://example.com/wp-admin/">Have fun!</a></p><p>Remember to update the passwords and roles of imported users.</p>

despite the --quiet flag

Closing in favor of https://github.com/WordPress/wordpress-importer/issues/141, as it should really be fixed there.
