Fix editing file in local client

After synchronizing a folder in drive, if we edit a file locally, drive just stays synchronizing infinitely and the change is not made in the remote client.

How to reproduce

• download the latest daily build(mine was nuxeo-server-10.10-I20190107_0125-tomcat.zip )
• install drive, web-ui and showcase-content addons
• In webui go to Workspaces >> Sample Content >> Notes and sync that folder
• still in webui edit the Lorem ipsum note
• wait for drive to sync and check that the changes were made also in the local file
• edit the Lorem ipsum note locally
• drive stays synchronizing infinitely and no change is made in the remote file
