// This hijack is important to make sure, collections created before
// we hijack dbOps, even gets tracked.
//  Meteor does not simply expose MongoConnection object to the client
//  It picks methods which are necessory and make a binded object and
//  assigned to the Mongo.Collection
//  so, even we updated prototype, we can't track those collections
//  but, this will fix it.
