Fix centering dialogs

QDialog::setVisible() tries to adjusts the dialog position, but
it's not really possible if the dialog size is not defined yet.
Besides, if the dialog window is not created, QWidget::move()
will not really move it and will set WA_PendingMoveEvent flag.
And QWidget::setVisible() also will not change the position,
because we reset WA_Moved flag. Thus it may break adjusting
the position in QDialog::showEvent().

So adjust the position only in QDialog::showEvent().
