CAP - Importing From CSV File -NULL

With CAP in local, after running CDS deploy, matched CSV or json files can be loaded into corresponding tables. If a table's last colum is nullable, but during file importing, empty char is inserted for this column. The reason is a bug in below code. At line 26, it provides undefined for those without values. But miss this logic for last colum at line 47. Just like line 26, adding '|| undefined' is able to fix this easily.

The CAP version is 3.30.0.
