Locally synchronized file name is not updated following changes made directly on the plateform

Steps to reproduce:

• create a folder through the web client and synchronize it
• add a file in the folder through the web client (a .doc for example)
• wait for the document to be synchronized locally
• update the file through the web client (replace the .doc file by a .pdf)

==> the file is updated locally but the filename has not changed which results in an error when opening the file (in this example MS Word cannot open the pdf file)
