Fix insert and scroll to bottom case
When using QtextCursor::insert() with a large text followed by setting
the vertical scrollbar to its maximum value (scroll to bottom),
QPlainTextEdit would not behave properly if a document size
change was triggered by the insertion due to line wrapping.
This was visible in Qt Creator.
Auto test included.
