If the processing date was left blank in 'Report Production Ready', the 'Physical Date' was not filled in on the sub-assembly

If the processing date was cleared in the Report Production Ready action, the Physical Date field on the sub-assembly was not filled. In this situation, Physical Date is now filled with today's date. This solution is also applied if sub-assemblies are reported ready via an API call (s_actie_aantal_gereed) where t_verwerk_datum is not filled.
