REVISION SUMMARY
  If there's no data, it looks like it's bugged. Let's hide it in such case.
  
  Similar to: D27403 <https://phabricator.kde.org/D27403>

TEST PLAN
  1. Start khelpcenter
  2. Open every top level menu item
  3. Every top level item shouldn't be empty
  
  For me, top level items "Konqueror Settings Modules" and "Other Settings Modules" are empty. With this change they'd be hidden instead.

REPOSITORY
