Fix unexpected keyword argument 'allow_abbrev' error
The MR 79684 fix args' clash in CTest but broke one ART test test_poolMerging_data23.sh reported by @tsulaia at 79684 with error reported by me at ATEAM-1075.
This MR fix(by just accessing the allow_abbrev properly) that broken ART Test with no error.
