Made QInputDialog::getText() return null QString when rejected

This reverts a behavior change introduced with Qt 4.5.0 where
QInputDialog::getText() returned the line edit's text when the dialog
was rejected.

However, the behavior since Qt 4.0 has been to return a null QString
when the dialog is rejected.
