Title: Fix data type bug in `redis-cli` command

While stubbing out `Kernel.system` for the `redis-cli` command, I missed that
`Kernel.system` only takes strings as arguments, so the port number must be
converted to a string. Avoiding the conversion on hostname and password
because Heroku Redis providers will always require a password.

Fix #17.
