[pmachapman]

Fixes #1020

I was able to recreate this locally by stopping the mongo-1 docker container, then restarting it after a couple of minutes.

src/Machine/src/Serval.Machine.Shared/Services/LocalBuildJobRunner.cs line 116 at r1 (raw file):

                // If one of the tasks has faulted, cancel the other
                if (completedTask.IsFaulted)

Is this scenario testable?
