Remove redundant restart

We don't need to restart Elasticseach after this task. Everything is set
in a similar task earlier. This one is only to change the start
bevaviour to a safer one (not reinitializing the cluster). The change is
only needed during restarts, so whenever Elasticsearch is restarted, the
new version will be used.

fixes #278
