This can cause issues, though it should be noted that the majority
of the time this will marshal/unmarshal just fine, see

* bugfix: sqlite migration should handle create events as having no 'before' snapshot
The state snapshot for any given event in the roomserver represents the state _before_
the event. For the create event, this is nothing, so the state snapshot nid should be 0.
In some cases this wasn't happening, resulting in a nice mix of possible options including:
- A state snapshot without any state blocks `[]` or `null`.
- A state snapshot with a single state block with a single event, the create event, causing
a circular loop. This is incorrect as it represents the state before the event, not after.
* Add state key check
