Case Start Date and End Date don't work properly in Batch Update
When trying to batch update a case start date or end date you get the following error: Notice: Undefined index: formatType in CRM_Utils_Date::addDateMetadataToField() (line 1878 of /srv/buildkit/build/dmaster/sites/all/modules/civicrm/CRM/Utils/Date.php).
This results in Start Date: the current date being filled into all values End Date: if it's not already filled in, you can only select today's date.
