Sukchan Lee 6124908133 Handle UL NAS Transport [#553] 
o Tester
1. UE registered to 5GS and can connect to internet.
2. Turn off the UE and turn on the UE immediately
3. UE send PDU session request message
   without sending registration complete

o Analysis Result
1. UE sends registration request with unknown GUTI
2. AMF send registration accept without GUTI
3. UE skips the registration complete

So, we need the handler UL NAS Transport in this state.
