Change streaming server to treat blank redis password as password-less auth (#14135)

Fixes #14131

Our `mastodon:setup` task defaults to a blank password rather than the
absence of password, but some versions of Redis reject blank password
authentication when authentication is possible without a password.

The Ruby code only uses the Redis password when it's not blank, so
do the same for the node.js part.
