Subject: [PATCH] When deleting a focus scope the hasFocus() flag is not
 cleared for the item having the local scope. In situations, where the
 focusScope is no parent ( only a parentItem() ) and the focusItem gets
 reparented we run into an invalid situation with a wron focus flag. To work
 around this Qt bug we manually clear the focus flag.
