Base Model properties are not resolved when extended

[kendzi]

I fall down into the same problem as described in swagger-api/swagger-ui#1723 I try to debug it and I think the problem is with swagger-js not the ui. Here I created simple junit test (in resolver.js):

  it('base model properties', function(done) {

        var api = new Resolver();
        var spec = {
          swagger:'2.0',
          info:{    
          },
          host:"localhost:9000",
          schemes:[
            "http"
          ],
          basePath:"/2.0",
          paths:{
            '/':{
              get:{
                responses:{
                  "200":{
                    description:"Pets",
                    schema:{
                      "$ref":"#/definitions/Pet"
                    }
                  }
                },
                parameters:[
                ]
              }
            }
          },
          definitions:{    
            Cat:{
              allOf: [
                {
                  "$ref": "#/definitions/Pet"
                }, 
                {
                  type: "object",
                  properties:{
                    size:{
                      type: "number"
                    }
                  }
                }
              ]
            },
            Pet:{  
              type: "object",    
              properties:{       
                color:{
                  "$ref":"#/definitions/Color"
                }
              }
            },
            Color:{
              "type": "string"
            }
          }
        };
        api.resolve(spec, 'http://localhost:8000/v2/swagger.json', function (spec, unresolved) {

          expect(spec.definitions.Pet.properties.color['$ref']).toBe('#/definitions/Color');
          expect(spec.definitions.Cat.properties.color['$ref']).toBe('#/definitions/Color');

          done();
        });
    });

It fails because method as the result returns values like: "http://localhost:8000/v2/swagger.json#/definitions/Color".
I'm expecting here to get "#/definitions/Color" even if it is used by "inline" object. Is it right assumption?
