When provided callback to validate() throws an error that callback is being called again.

[ujasur]

Message validator has the issue of calling the provided callback twice. It can cause error where it is assumed that function will be called once. For example:

var v = new MessageValidator('someurl');

function middleware(req, res, next) {
   v.validate(validMessage, function(err, message) {
       console.count('called');
       if (err) { 
          return next(new Error('Validation error:' + err.message )); 
       }
       // some code
       throw new Error('inside callback');
   });
}

Any news on this? I am considering using this module, but this looks like a showstopper.
