QMLManager::changesNeedSaving() behaves differently on iOS:
it only saves locally with saveChangesLocal(), whereas all
other OS save to cloud with saveChangesCloud(). Nevertheless,
even for other OS saveChangesLocal() is called even though
that will be called in saveChancesCloud anyway. Therefore,
compile the saveChangesLocal() call in changesNeedSaving
conditionally.
