Local move randomly not detected as a move but a deletion + creation under Windows (and Linux)

See the difference between:

• A successful build: http://qa.nuxeo.org/jenkins/view/Drive/job/FT-nuxeo-drive-master-windows/288/consoleFull
  Where we can see:

  Detected a file movement LastKnownState<local_folder=u'Nuxeo Drive', local_path=u'/Nuxeo Drive Test Workspace/Original Folder 1', remote_name=u'Original Folder 1', local_state='deleted', remote_state=u'synchronized', pair_state='locally_deleted', error_count=0>
  

  which leads to a remote move as expected:

  Moving remote file according to local : LastKnownState<local_folder=u'Nuxeo Drive', local_path=u'/Nuxeo Drive Test Workspace/Original Folder 2/Original Folder 1', remote_name=u'Original Folder 1', local_state=u'moved', remote_state=u'synchronized', pair_state=u'locally_moved', error_count=0>

  We can see no Detected a file movement ...
  => We get a remote deletion which is not expected:

  Deleting or unregistering remote document 'Original Folder 1' (defaultFileSystemItemFactory#default#5843594b-394a-4ef5-8064-6475be63622e)
  

  then a call to:
