Remove logging on invocation of ApplicationExtended.canLogon(sessionID)

problem

Inside the Session.next() method, the callback ApplicationExtended.canLogon(sessionID) is invoked. However, each time the next() method gets called (i.e. each second) and canLogon is FALSE a log line is created:

"Do not initiate logon, Application can not logon on <sessionID>"

This logging should be removed as that log output could be implemented in the specific application. There is no logging output for the other callbacks (onLogon, onLogout, ...) either.
