Qt: Plug leaks in Conversations/Endpoints windows

Set some models to have the Traffic Tab or Traffic Type List
that creates them as parent, so that they will be deleted
properly. Setting a model does not cause it to be deleted
unless it is parented, because models can be shared among
multiple views. Since these models are only used by the
one view, parenting them is fine.
