Two folders having the same name, except one with a trailing space character, are displayed two times

[mathpce]

When two folders are named identically, to the exception to a trailing space for one of them, both of them are displayed two times.

Note that their content is also displayed as being the same, see #78.

This is a problem not limited to the File Manager app. I've seen it also in the Navigation Panel and in the Breadcrumb, but the issue was not reported here.
See this forum thread and these related issues: XWIKI-11617 and XWIKI-14354

Versions:

• XWIKI 15.4
• File Manager (Pro) 2.6

To reproduce the bug:

1. open the file manager application
2. create a new folder named "testTrailingSpace" (without the quotes)
3. create another new folder named "testTrailingSpace " (note the presence of the trailing space)
4. see that each one is displayed two times

Note: the name of the folder needs to be one never used before (even for a deleted folder) because the page reference wouldn't be the same as the title (you would have "testTrailingSpace1" and "testTrailingSpace " for instance ).
