Description: Unit test for NFC LLCP server sync(waitXXX) functions
TestScenario: 1. Server will listen to a pre-defined URI
2. Wait client to connect.
3. Read message from client.
4. Echo the same message back to client
5. Wait client disconnect event.
TestExpectedResults:
1. The listen successfully set up.
2. The message has be received from client.
3. The echoed message has been sent to client.
4. Connection disconnected and NO error signals emitted.
