URI passwords not percent decoded

[nolta]

If my password contains "/", and I want to pass it via the URI, I have to percent encode it. For example, if my password is "a/b", the URI might look like:

redis://:a%2Fb@localhost

However, the password isn't being percent decoded, and so the connection fails.

@nolta interesting, I think we can give that a try as I don't see it causing backwards compatibility issues. Would you be willing to get a PR up? 🙃

@nolta gentle ping 😌
