Fix escaping issue when retrieving child sync roots

1. install nuxeo 7.10
2. install nuxeo-drive add-on
3. in the personal workspace create a document of type File, containing a quote
4. modify the permissions of this document
5. logs show the following stack trace:

The issue is in NuxeoDriveFileSystemDeletionListener and Path:

    protected List<DocumentModel> getChildSyncRoots(DocumentModel doc, CoreSession session) {
        String nxql = "SELECT * FROM Document WHERE ecm:mixinType = '" + NuxeoDriveManagerImpl.NUXEO_DRIVE_FACET
                + "' AND ecm:currentLifeCycleState != 'deleted' AND ecm:path STARTSWITH '" + doc.getPathAsString()
                + "'";
        return session.query(nxql);
    }

The path retrieved by doc.getPathAsString() is unescaped.
