Pea Tyczynska 52dbdb7518 Move validate_and_update_broadcast_message_status to a utils file
This is because that function is used both when broadcast status
is updated via API and via admin, so it's a shared resource.

Also move and update tests for updating broadcast message status
so things are tested at source and repetition is avoided.
