Hudson Tray Tracker still has the old server installation after uninstall

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Uninstall the application
2.Add new Jenkins Server url
3.Select some jobs

What is the expected output? What do you see instead?
After reinstall of the application, it should not be aware of the old 
information as all the old server information should be lost, but in my case 
old server urls and jenkins jobs i configured are still present.

What version of the product are you using? On what operating system?
0.12.3.0

Please provide any additional information below.
I am trying to add the new jenkins server but Tray Tracker is still pointing to 
the old one.
