[Rework] Breaking: Do not report soft reject in history
We can have much more clear information if we store the real action in
case of `soft-reject`. In this case, we can just imply that a module
that has set this action is an action itself, such as:

* greylist
* ratelimit
* multimap
* antivirus rule name

This policy seems quite reasonable, as `soft reject` has no meaning on
its own.
