LPS-36643

While working on LPS-36458, I had to reach the 'real' target class of proxified class in code like this. I used `AopUtils` for that (common approach) and it happened that Advices methods are also proxified, so calling `getTargetSource` would run into endless recursion.

Hopefully, we do have better wayout from this, and Ray has replaced it with usage of `ProxyUtil` and `#getAdvisedSupport()` from `HookHotDeployListener`, making the addon in `ServiceBeanAopProxy` obsolete.
So now we just have to rollback the code
