Rails 5.2 application fixes

- Rename before_filter → before_action across all controllers
- Fix string conditions in validators to lambda syntax (node.rb)
- Fix publish_draft!: move staged slug/parent logic outside draft guard,
  use move_to_child_of for parent changes, add nil guard for no-op calls
- Fix update_unique_names_of_children: use parent_id traversal instead
  of lft/rgt descendants (awesome_nested_set 3.x lft/rgt update bug)
- Fix unique_path to return Array instead of String
- Fix Occurrence.delete_all syntax for Rails 5
- Fix Page.find_with_outdated_translations: use includes instead of all
- Fix outdated_translations?: use find instead of splat array
