After upgrading to 6.2.x, the root folder in 'display settings' is not set to the folder that we selected in 6.1.
Steps to reproduce:
1. In 6.1.20, we add a new page 'test page'-> add 'Document and Media' portlet into this page.
2. Go to 'Configuration' page of 'Document and Media' portlet -> Choose a new folder 'test' to be the root folder under 'Display Settings' section.
3. Upgrade to 6.2.x. -> Got to 'test page' -> Go to ‘Configuration' page of 'Document and Media' portlet.
4. Observe the value of root folder under 'Display Settings' section.
Current behavior: There isn't any value under the 'root folder' section. Please refer to '6.2.PNG'.
Expected behavior: 'test' folder should be selected after upgrading.
