In Job Chain View Order's "Next Start Time" should always be displayed

Current Situation

• In the Job Chains view when a user adds an Order to a job chain with a stopped job node then the Order waits in front of this job node and its next start time shows "never".
• When the Order is reset from its action menu then it shows the period "Running since" and also the time increases continuously.

How to reproduce

• Login to JOC Cockpit.
• In the Job Chains view add an Order to a job chain for immediate execution.
• Set one job to stop using "stop node".
• Start an Order and wait until it reaches the stopped node.
• Reset the Order from action menu.
• As a result the Order moves back to the first node of the job chain but still shows the "Running since" period.

Desired Behavior

• The Order should move back to the first node in the job chain when being reset, should show "Next Start: never", however, the "Running since" period should not be displayed.

Maintainer Note

• If you "reset" an order then no new order run is created. It is still the same order run and it has a "running since" from its first start.
