When KB Display portlet has more that one folder available, and the user changes folder, the portlet should show the article inside the new folder with the same ultTitle as the original one.

Steps to reproduce:

• Go to Admin > Content > Knowledge Base
• Create a "Test" folder
• Inside the "Test" folder create two folders called "1.0" and "2.0"
• Inside "1.0" create two articles called "article 1" and "article 2" (don't modify the provided friendly url).
• Inside "2.0" create the same two articles
• Go to a public page
• Configure a Knowledge Base Display portlet to show articles inside the "Test" folder.
• In the navigation, choose the "1.0" folder in the combo.
• Select the "article 2" in the navigation.
• Select the "2.0" folder in the combo

Expected result:

• The "article 2" inside "2.0" is shown
  Actual result:
• "article 1" is displayed to the user
