Fix suboptimal page slugs
To avoid problems with duplicate slugs and missed content,
drupal2lektor was modified to use the
node-[nid] as the slug when a node was missing a URL alias in Drupal. Furthermore, some aliases containing a
events/ upper directory were changed to
events-, again to prevent any issues with duplicate content cause missing pages.
Once the import is complete, we should go over those to generate a new URL slug based on the title, taking care to manage duplicates correctly (eg. by adding a suffix).
