CallModel::index() ASSERT when called on child of conference
Issue generated from Tuleap's migration script. Originally submitted by: Stepan Salenikovich (ssalenik)
if parent is a conference and row corresponds to the index of one of its child calls, calling CallModel::instance()->index(row, 0, parent) seems to cause an ASSERT (at least when called during CallModel's rowsInserted signal).
It seems that in the ::index() function, the parent is detected as invalid... something weird is happening...
