make columns non-NULLABLE

* We don't want orphan journeys, so having owner_id NOT NULL is clear.
* We don't want no titles, that's basically the point of journeys.
* We could allow NULL for descriptions, but it seems silly -- we can
  always allow the empty string, and we don't meaningfully distinguish
  between them in the UI anyway.
* We don't want an unspecified visibility, so that's NOT NULL.
* We could imagine having a link secret of NULL, to potentially disable
  link sharing for a journey, so we keep this field nullable.
