Selecting many tracks in the AutoDJ queue may freeze the GUI

Bug Description

Reported here https://mixxx.discourse.group/t/i-did-something-stupid/28750, and confirmed.

I suspect it's the function that updates the track count and play duration of the queue.

mixxx/src/library/autodj/dlgautodj.cpp

Lines 365 to 375 in f610d58

	void DlgAutoDJ::updateSelectionInfo() {
	double duration = 0.0;
	QModelIndexList indices = m_pTrackTableView->selectionModel()->selectedRows();
	for (int i = 0; i < indices.size(); ++i) {
	TrackPointer pTrack = m_pAutoDJTableModel->getTrack(indices.at(i));
	if (pTrack) {
	duration += pTrack->getDuration();
	}
	}
