user_recs returns recommendations that a user already knows #2

Hello again,

In this example: 

[
  {user_id: 1, item_id: 1, value: 1.0},
  {user_id: 2, item_id: 1, value: 1.0},
  {user_id: 2, item_id: 2, value: 1.0},
  {user_id: 2, item_id: 3, value: 0.0}
]

recommender.user_recs(1, count: 3) returns item 1 as the highest score even though it's value is already known.

Looks the same as this issue in the other library: https://github.com/ankane/disco/issues/6

I just pushed a new release you can use.

The shared libraries aren't included in the Git repo, so to use an unreleased version, you'll need to fork the gem, download the shared libraries (bundle exec rake vendor:all), update .gitignore so they can be committed, and then commit them to the fork.
