Ensure forward models after running ones are pending

When realizations are resubmitted after failures, the snapshot shows
information from the previous run. This commit modifies the forward
model state of forward models following any Running state for a
realization to make sure they are set to Start/Pending.

The GUI will thus show correct colors for these forward models, but
error messages from the failed previous run are still available from the
GUI.
