Remote trashed document is put in the local trash of the user

Scenario:

• User 2 synchronises a folder locally
• Remotely, user1 delete a file
• The file is put in the local trash of user2

If user2 chooses to "put back" locally, the file is not undelete remotely and is put in error.

Expected behavior:
Deleted file by user1 should not be put in the local trash of user2 but should be deleted.
This avoid to synchronize too many files
