leshan: Bootstrap Server 2.0.0-M5 upgrade: problem with ConnectionListener

Hi guys.

I’m upgrading the Bootstrap Server from 2.0.0-M4 to 2.0.0-M5. In my server configuration, I have the ConnectionListener registered in DtlsConnectorConfig. My implementation listens to the void onConnectionRemoved(Connection connection) event to handle DTLS connection error.

In version M4 I invoked connection.getSession() and connection.getOngoingHandshake() to gather some detailed information of the DTLS session. However in M5 the both methods return null instead of correct objects.

For me, it looks like a regression. Can you please advise?
