list-simulations is incomplete

list-simulations does not distinguish between active and inactive simulations. Only active simulations have a current restart.

Also, a simulation can never be "HELD", since this indicates a presubmitted restart (and is not a simulation state).

If a simulation has no valid restarts, then it is simply inactive, and a restart was never submitted. The message "skipping" sounds as if there was a problem, but there is none.
