Avoids potential rounding of -inf time delta in TaskQueuePacedSender.

This rounding triggers a dcheck that crashes debug builds.

Furtunately, in release mode this does not matter as the resulting
value is anyway capped to 0.

Unfortunately, it is almost impossible to write a test for this even
with simulated time as the conditions needed to trigger this condition
includes thread scheduling being slightly off in such a way that an
unscheduled process call preempts a scheduled one at a time when
sending a sufficiently large padding packet becomes possible - and
right after starting a new probe cluster.

We should consider updating this class to make unit testing easier.
