MongoStore.destroy not removing the stored session

[benpusherhq]

I unfortunately don't have a simple test case to recreate for this. In my application, req.session.destroy() was not removing the session data from the database (effectively disabling the "sign out" functionality).

I found it have something to do with the callback being passed to remove. Changing the code to pass a valid, but noop callback fixed the issue.

    destroy: function (sid, cb) {
        MongoStore.client.remove({ sid: sid }, cb || function(){});
    },

The associated versions of modules I'm using are:

• express@3.2.6
• mongoose@3.6.11
• express-sessions@1.0.5

By the way, thanks for sharing this module!
