* Replace current onboarding notification with set_up_profile welcome notification
Also ensure that only "active" set_up_profile welcome notification is sent, and that "inactive" ones are ignored.
* Notify only if broadcast active, log error if broadcast not found
* Reports to Honeybadger if an active broadcast cannot be found
* Reorganize order of generator specs
* Ensure welcome_broadcast can be written to in spec
* Remove redundant spec
