ListModel::clear() should not clear roles
Clearing a model and then appending a new object with a subset of the
previous roles was causing a crash since ListModel cleared the roles
and VisualDataModel did not, so VisualDataModel was requesting invalid
roles. This could have been fixed by clearing the meta object and
its property cache in in VisualDataModel but this is less efficient,
and also the general use case is for model data to always have the same
roles.
