Excluding attributes with scope.

The key 'titleAttributes' on line 2590 seems to be incorrect. Should be 'attributes', causes a crash when excluding attributes with a scope.

/Users/username/Documents/project_name/node_modules/sequelize/lib/model.js:2590
    var attributes = Object.keys(this.tableAttributes);
                            ^
