Mikael Nordfeldth 63c087a255 Consistent behaviour for ScopingNoticeStream $scoped
We don't guess the current profile anymore if the value of the profile === -1

Also sets $this->scoped for all ScopingNoticeStream inheritors, which just
like in an Action can be null if we're not scoped in any way (logged in).
