Properly trigger security session events from facebook workplace #1109

[ariel-learningpool]

This should fix issue #1109 and properly trigger security sessions events without breaking existing functionality.

You should be able to catch events with controller:
controller.on('log_in', function(bot, message) {} );
controller.on('log_out', function(bot, message) {} );
