QComboBox: emit currentIndexChanged() and currentTextChanged() when the model is cleared
QComboBox uses QPersistentModelIndex to store the current index of the
underlying model. When the model is cleared, that index is automatically
invalidated, so calling QComboBoxPrivate::setCurrentIndex(QModelIndex())
does not result in signals being emitted, because we do not detect the
index change.
This patch uses indexBeforeChange to detect such situation and emit all
necessary signals.
