OC PhySim deployment: always undeploy safely

This fixes basically two problems. First, remove "set -e", which leads
to the script exiting on error. For instance, there was the sleep which
should account for the time of the pod being in "ContainerCreating", but
might not be enough. In that case, the script would exit, leaving the
pod deployed.

Second, a fixed time is not good, as it can be too short and unduly
prolong waiting time. Replace with a loop.
