QWidgetTextControl: don't clear() a new empty document
Before: 0.063 msecs per iteration
After: 0.054 msecs per iteration
clear() takes time because:
1) QTextDocumentLayout::documentChanged() => doLayout() => layoutFrame()
2) QTextDocumentPrivate::init() => insertBlock() => finishEdit() =>
QTextDocumentLayout::documentChanged() => layoutStep() => ... => doLayout() again
Pick-to: 6.3 6.2
