[glib/wip/smcv/2452-g-string-0-length-replace: 4/5] test_string_replace: Exercise zero-length replacements

    test_string_replace: Exercise zero-length replacements
    
    Previously, these would have done 2**32 replacements, and the first one
    would have consumed 6GB of memory in the process. They now match what
    Python `str.replace()` does.
