Can't set delay to greater than 24 days

Created by: tanqhnguyen

It seems that when you set the delay to more than 24 days, the job gets executed immediately.

I take a look at the test https://github.com/OptimalBits/bull/blob/master/test/test_queue.js#L869, and change delay to 24*30*3600*1000 (30 days), the test still passes immediately which is weird

Btw, the expect statement seems to be wrong (I am not sure, but I think it should be expect().to.be(true))
