Change Test for Issue 14422 (Cognitive Complexity lowered through mul… (#14603)

changelog: [cognitive_complexity]: Changed Test for this issue from
making sure its not a false positive to making sure its not a false
negative which was the original issue at hand. The test as it was would
also not fail without the change introduced. This test will show if any
regression is made in further pushes.
