[8] Review request for 7124326: [macosx] An issue similar to autoshutdown one in two AppContexts situation.

[Anthony Petrov]

Hi Artem and Leonid,

Please review a one-liner for 
http://bugs.sun.com/view_bug.do?bug_id=7124326 at:

http://cr.openjdk.java.net/~anthony/8-38-AppContextAutoshutdown-7124326.0/

A SystemTrayPeer instance added to a peers map prevents an app from 
exiting. On other platforms we don't add the SystemTrayPeer to the map 
(only the TrayIcon peers get added). So I implement the same logic on 
the Mac by removing a call to targetCreatedPeer() from 
LWCToolkit.createSystemTray().
