Orders are not rescheduled correct after JobScheduler restart.

Current Situation

An order has a run-time like this

 <run_time  schedule="test"/>

and the schedule test looks like this

<schedule  name="test"/>

The next start time is calculated to "never"
The order is executed manually from JOC Cockpit

Looking in the database table SCHEDULER_ORDERS there is then an entry that have in the attribute order.xml this

<order at="2038-01-19 03:14:07.000Z" 

what means never.

When now a schedule is created like this

<schedule  valid_from="2020-04-03 00:00:00" valid_to="2020-04-07 00:00:00" substitute="test" name="schedule2">
    <weekdays >
        <day  day="1 2 3 4 5 6 7">
            <period  single_start="14:00"/>
        </day>
    </weekdays>
</schedule>

the run-time of the order is recalculatet to 14:00. The entry in the database is unchanged. When the JobScheduler is restarted in this situation, the run-time for the order is calculated to "never" what is wrong.

Desired Behavior

After restarting JobScheduler all run-times should be calculated correctly.
