Support Data Validations in More Versions of Excel

Attempt to deal with PHPOffice#2368, this time for good. Some deleted code was accidentally restored just before release 19, causing errors in spreadsheets with Data Validations. PR PHPOffice#2369 removed the duplicated code, and the fix was confirmed in current versions of Excel for Windows, Google sheets, and other versions of Excel. However, there were problems reported in earlier version of Excel for Windows, and some, versions of Excel for Mac, not all but including a recent one. This change, which is simpler than the original (no need for extLst) fix for DataValidations, is tested with Excel 2007 and Excel 2003 as well as more recent versions. I do not have a Mac on which to test.
