In dev branch we already updated SignalR Redis scale-out using StackExchange.Redis instead of BookSleeve, but the latest Microsoft.AspNet.SignalR.Redis package from http://myget.org/F/aspnetwebstacknightly/ still has old dependency BookSleeve.

Functional impact:
The latest Microsoft.AspNet.SignalR.Redis package from http://myget.org/F/aspnetwebstacknightly/ can't work now.

Repro steps:

1. Install the latest Microsoft.AspNet.SignalR.Redis package from http://myget.org/F/aspnetwebstacknightly/

Expected result:
The new dependency StackExchange.Redis package is installed.

Actual result:
The old dependency BookSleeve is installed instead of StackExchange.Redis.
