Ensures that text elements are deleted after the entire text editing process is finished. Previously elements were deleted on next Score::update() call which is dangerous since it may happen to be called several times on finishing text editing. Also take care to remove the deleted element from selection to prevent potential crashes on undo/redo operations (e.g. with lyrics)
