desktop: avoid crashes on drag&drop in GroupedLineEdit
If the user manages to "scroll" through the QPlainTextEdit by
a drag&drop action, the state of the widget becomes inconsistent.
On the one hand, the text-block says that it has one line.
On the other hand, its layout says that it has no line.
When trying to fetch the line, a crash occurs.
Try to detect such a strange state and return early in
GroupedLineEdit::paintEvent().
