REVISION SUMMARY
  Fixes memory leak of KItemListHeader
  The KItemListHeader passed the listView parent object to the QObject
  base class, but that pointer seems to always be nullptr causing the
  KItemListHeader to not be memory managed by anything. Instead simple
  use the listView as parent pointer.

TEST PLAN
  This leak was found using Address Sanitizer
