Fix bad logs in 404

[lautaroalvarez]

In app.js file there is a bad log inside an app.use:

    app.use(function(err, req, res, next) {
        logger.error('handleError: ', err);
        if (res.headersSent) {
            return next(err);
        }
        let error = {};
        error.status = err.status;
        if (req.app.get('env') === 'development') {
            error.message = err.message;
            error.stack = err.stack;
        }
        return res.status(err.status || 500).json({
            error
        });
    });

Remove the logger.error('handleError: ', err); and verify if there is other bad logs in the code.
