Populated type column of existing events (#14437)

Browse source 
refs https://github.com/TryGhost/Team/issues/1302

Currently we only have three event types: created, updated & expired.

A created event always has a `from_plan` of null

An updated event will always have a different `to_plan` and `from_plan`
as the subscription has changed tier/cadence.

An expired event _should_ have a `to_plan` of null, but due to a bug we
have events with the same `from_plan` and `to_plan`.
