Avoid panicking on wallclock time going backwards across restart

Because we serialize `Instant`s using wallclock time in
`ProbabilisticScorer`, if time goes backwards across restarts we
may end up with `Instant`s in the future, which causes rustc prior
to 1.60 to panic when calculating durations. Here we simply avoid
this by setting the time to `now` if we get a time in the future.
