Slim factories need to be in puli.json.

For future reference. This is how I did. (Ping @tuupola)

$ php puli.phar bind -f Http\\Message\\MessageFactory\\SlimMessageFactory Http\\Message\\MessageFactory
$ php puli.phar bind -f Http\\Message\\MessageFactory\\SlimMessageFactory Http\\Message\\ResponseFactory
$ php puli.phar bind -f Http\\Message\\MessageFactory\\SlimMessageFactory Http\\Message\\RequestFactory
$ php puli.phar bind -f Http\\Message\\StreamFactory\\SlimStreamFactory Http\\Message\\StreamFactory
$ php puli.phar bind -f Http\\Message\\UriFactory\\SlimUriFactory Http\\Message\\UriFactory

Am I correct that for discovery to work without Puli Slim factories should also be added here?
