QQuickItemView: fix crash when changing model

When visible items become invisible, ListView will try to cache
them and redisplay these items if necessary. However, we can't
cache items when changing to a new model, since the old one will
be deleted later

Fix by adding a flag to let ListView know we are clearing items
and prevent cache unnecessary items
