By rogerbraun:

I had to extend here, too, in SQLite, or else the first ID would not be set, as the logic in #add in bundle_realtime.rb is something like this:

```ruby
list = backend[key]
list = backend[key] = [] unless list
list << something
```
So if there is nothing in backend[key], a naked Array will be the value of list.
