Merged requested to merge DEICH-6429-manned-opening-hours into master
DEICH-6429 - Fixed arrogant date monster
It was just creeping through the deviating hours like hell. Until today. Now this bastard was caught, and eliminated. Reason for the bug was that EditInterval did not allow for setting the periodStart/periodEnd besides the initial setup. Now there was made a change to set the interval ends in flatpickr as these props are set, and fire the interval change in the flatpickr options hook. It was actually he opposite before, thus causing problems.
DEICH-6429 - Added cleanup logic for meråpent
Now the deviating hours are set correctly. - normal opening open flag is set to true; - openFrom/To is set to mannedFrom/To - manned, mannedFrom/To is deleted.
