REVISION SUMMARY
  A `new KFileMetaData::UserMetaData` is only created when a single file is selected.
  If more files are selected, we will call `delete` on garbage memory and crash.
  Calling `delete` on a `nullptr` is safe.
  
  BUG: 401733

TEST PLAN
  - Selected multiple files, opened context menu, closed context menu, no crash
  - Selected single file, opened context menu, Tags menu still worked
  
  This feature is only in master, not 18.12, right?

REPOSITORY
  R824 Baloo Widgets
