PCU_Tests: verify that PacketCellChangeContine contains an ARFCN and BSIC 

The testcase TC_nacc_outbound_success tests the NACC procedure. The cell
that is proposed in the PacketCellChangeNotification is a GERAN cell.
This means that the PCU should conclude the procedure with a
PacketCellChangeNotification that contains the ARFCN and BSIC of the
proposed cell. Let's make sure that this actually is the case.
