A timer in QB_POLL_ENTRY_JOBLIST doesn't necessarily have a t->timerlist_handle so that deref can segv. Also the comment assumes the timers are threaded - which as we have decided is definitely not true. So it's safe to move the check earlier.

In the tests, I've adjusted the timeouts so that they definitely happen at different times. On some architectures they can fire concurrently and in the wrong order.
