Feedback from Java Integration (#8272)

* ensure we get the exact same version of the list. this is probably paranoia but nothing telling we can't do it
* make it so that a crashing body key sanitizer is logged, but doesn't kill the sanitization session
* handle when the targeted path actually exists before attempting to secret scan it
* remove duplicate sanitizer
