Bug 36552: Update record 'date entered on file' when duplicating a record

The 'date entered on file' (MARC21: 008/0-5, UNIMARC: 100a/0=7) of a record created
by duplication of an existing record should be set to the current date instead of
having the value of the original record.

Test plan
=========
1. Check the 'date entered on file' of an existing biblio / authotiry record
   (MARC21: 008/0-5, UNIMARC: 100a/0=7).
2. Duplicate the record by Edit > Edit as new (duplicate)
3. Control the 'date entered on file' value - it will equal to that of the
   original record.
4. Apply the patch (restart plack).
5. Repeat step 2.
6. Check the date - it should be the current date.
