this makes all timers in these tests busted since the time is not actually
monotonically increasing?

I think they're already busted since this particular mock class doesn't support
delayed tasks.

Adding some ASSERT_NOT_REACHED(); seems like the right thing to do here in case
some future test code ends up calling these.
