Fix regression in emitting of QTextDocument::undoCommandAdded()

The test I wrote was not testing if calling undo/redo had any effect
on emitting undoCommandAdded(), added these test cases and fixed the
QTextDocumentPrivate::endEditBlock so we now again emit only when an
undo command is added, not also on calling undo or redo.
