runStatus changes to COMPLETED before run finishes logging

[willr3]

The GenericBenchmark.start() changes runStates to Run.COMPLETED but there are still several run related steps that can log to the run log or potentially hang. I do not see a runStatus to indicate the run is COMPLETED and all run logs are no longer active. I propose we either change where the run is marked COMPLETED or add a new status to indicate the run is no longer changing any of the artifacts.

It looks like you are integrating with another piece of software. That hoovers up these artifacts after Faban has manage a run. The obvious thing is to move the assignment and it's enclosing if block to line 326. Can you try testing that to see if that solves your problem? Then create a PR if it does.
