'cleanup_old_experiments' error when running from non-web (eg. console) about split

[jmccaffrey]

I had not seen the steps described in the wiki
https://github.com/splitrb/split/wiki/Use-Split-outside-a-web-request

The key part is to pass a user reference (and know how an existing user is identified)
key = "user-#{user.id}"
ab_user = Split::User.new(nil, Split::Persistence::RedisAdapter.new(nil, key))

        trial = Split::Trial.new(user: ab_user, experiment: experiment) # << passing in the ab_user is the key
        trial.choose! # << now this doesn't fail

The readme can just be updated with the part about initing a user reference to pass to Trial.new, then trial.choose! won't fail

Hi @jmccaffrey thanks for the issue!

I fixed the readme on #716 it's also possible to load doingSplit::User.find(user_key, :redis) as a shortcut.
