fix : In rest service getFoldersAndFiles, name have the same value than title - EXO-79569

Before this fix, the rest service getFoldersAndFiles return an xml object representing a file. If the title have capital letters, and the filename have not, the propery name and title, are the same, both with capital letters
This fix ensure to use the file name in the property name
