Genex: Restore REMOVE_DUPLICATES preservation of empty elements
Refactoring in commit 72d116ee68 (GenEx: list oriented genexes use
cmList class, 2023-03-29, v3.27.0-rc1~205^2) accidentally caused
empty elements to be dropped by the `REMOVE_DUPLICATES` genex.
Fix it and add a test case.
Fixes: #25080
