Names containing brackets don't show up with WebDav

1. install nuxeo
2. login with any user
3. go to the personal workspace
4. import through drag and drop a test.txt file
5. on a Windows client, map a Z (or any other letter) to the nuxeo server. For instance:

   http://<SERVER_IP>:8080/nuxeo/site/dav
   

6. observe the test.txt file is readable through WebDav (see fileVisible.png)
7. go back to the Nuxeo UI
8. add a folder named trial[1] at the same location than test.txt
9. observe on the Windows client that nothing is now displayed, not even the file test.txt (see emptyFolder.png)
10. observe the following stack trace in the server logs:

11. in Nuxeo, remove the folder or rename it and remove the brackets
12. observe through the WebDAV client that the personal workspace is now correctly displayed and no errors are present in the logs

Expected behavior: there should be no error when trying to read a folder containing brackets. The brackets characters are valid both on a Windows OS and on a Nuxeo server.
