Reattach active calls after modem USB reset (MM)
Currently when the modem disappears (f.e. because of a USB reset) from DBus the call display for an ongoing call will be closed but the call might still be active.
When the modem reappears it would be good to "reattach" ongoing calls to a call display. Otherwise the user has no way of hanging up the call.
