maybe bugprone-exception-copy-constructor-throwable WDYT?

Agree that double-negation is hard to read, changed to `bugprone-exception-copy-constructor-throws` (changed `throwable` to `throws` because it sounds like [an object](https://docs.oracle.com/javase/8/docs/api/java/lang/Throwable.html) to me)
