Bug 1788016

Description of problem:

When "oc status" run, the following runtime error has been happened. It seems like a nil variable does not handle well.

https://github.com/openshift/oc/blob/release-4.2/pkg/helpers/describe/projectstatus.go#L950-L953
~~~
func describeJobStatus(job *batchv1.Job) string {
	timeAt := strings.ToLower(formatRelativeTime(job.CreationTimestamp.Time))   
	return fmt.Sprintf("created %s ago %d/%d completed %d running", timeAt, job.Status.Succeeded, *job.Spec.Completions, job.Status.Active)      <-- runtime error stack point here
}
~~~

* the panic error messages are as follows.
~~~
$ oc project openshift-logging
$ oc status
panic: runtime error: invalid memory address or nil pointer dereference
