Using Query.select() will break ParseObject.has() on undefined field

[dplewis]

Ref: parse-community/parse-server#3999
Caused: #409

  const obj = new Parse.Object('TestObject'); // Yay no foo
    obj.save().then(() => {
      const query = new Parse.Query('TestObject');
      query.select('foo');
      return query.get(obj.id);
    }).then((result) => {
      expect(result.has('foo')).toBe(false); // result.has('foo') returns true ?!?? :(
      done();
    }).catch(done.fail);

Up for grabs
