simex e kill does not mark experiments as killed

[bernlu]

When launching an experiment with slurm and killing the experiment while running with simex e kill, the experiment stays marked as started.

Example:

$ simex e list
Experiment                                    Instance                            Status
----------                                    --------                            ------
infinite                                      foo                                 [0] not submitted

$ simex e launch
