isTimeToGenerateLogon() in Session always returns true -> Initiators reconnect immediately when a Server closes the connection

The long attribute lastSessionLogon in Session never gets written and always stays 0. This makes isTimeToGenerateLogon() to always return true, because current Time - 0 will always be greater than computeNextLogonDelayMillis(). This results in Initiators reconnecting immediately and ignoring the ReconnectInterval after a Server closes the Connection.

This should affect all versions. But I only checked 1.5.1, 1.5.0 and TRUNK.

I am not sure where lastSessionLogon hast to be set, but I guess it should be in generateLogon(). Additionally I don't understand why lastSessionLogon gets set to 0 in nextLogon(). As far as I understand, it should never be necessary to reset it to 0. isTimeToGenerateLogon() is the only function that uses it.
