Fix overwriting the Healthcheck configuration from the image

If the --health-cmd flag is not specified, other flags such as --health-interval, --health-timeout, --health-retries, and --health-start-period are ignored if the image contains a Healthcheck. This makes it impossible to modify these Healthcheck configuration when a container is created.
