Disconnect slots from the old sourcemodel in QIdentityProxyModel
When setting a new sourcemodel QIdentityProxyModel::setSourceModel
tries to disconnect from signals belonging to the NEW model instead of
from the existing sourceModel(). QIdentityProxyModel thus receives
signals from both the old model(s) and the new model. This results in
ASSERTS triggering in various slots, for example:
"Q_ASSERT(topLeft.isValid() ? topLeft.model() == model : true);"
in QIdentityProxyModelPrivate::_q_sourceDataChanged.
