KTp Contact runner

[David Edmundson]

Not fully sure why it crashes but it's on this line:
            QModelIndex contactIndex = m_proxyModel->index(j, 0, accountIndex);

and somehow it's thinking some models have got mixed up

This is just a bit weird anyway, so do this

QModelIndex contactIndex =  accountIndex->child(j,0);

Dunno if that'll fix it, but it's a bit easier to read.
