Draft: small fix for older PathArray objects

Older PathLinkArray objects had a `useLink` attribute
which was migrated to `use_link`. A recent commit, ff323ebdb5,
made some improvements to the PathArray
object, but broke the migration of the property.

This fixes the migration, so that now all objects should
open correctly.
