REVISION SUMMARY
  Plasma-integration's KHintsSettings keeps kdeglobals open, so we need to explicitly `sync()` before we go through the process of telling everything it's changed

TEST PLAN
  Changing icons in the KCM affects everything immediately now

REPOSITORY
  R119 Plasma Desktop

REVISION DETAIL
  https://phabricator.kde.org/D14672

AFFECTED FILES
  kcms/icons/changeicons.cpp
