REVISION SUMMARY
  After D20623 <https://phabricator.kde.org/D20623>, some icons change a bit. This patch keeps the delegate using a trash can
  icon, and it's more semantically correct as well to use `edit-delete` over `list-remove`

TEST PLAN
  F6778140: Still a trash can here too.png <https://phabricator.kde.org/F6778140>

REPOSITORY
  R120 Plasma Workspace

BRANCH
  better-uninstallable-icon (branched from master)
