MSC_ConnectionHandler: expect additional MDCX when call is LCLS

The function f_establish_f_establish_fully does not yet handle the
case where calls get switched locally. In those cases we expect to
see one additional MDCX before the BSSMAP ASSIGNMENT COMPLETE is
sent.

- Check exp_ass_cpl if the call is expected to be LCLS and expect
  another MDCX for those cases.
