keystone-classic: [v0.3] Boolean fields with noedit:false and hidden:true do not retain value

Expected behavior

If a hidden yet editable boolean field has a true value in the database, it should retain it when it’s saved through the admin UI.

Actual behavior

The field will always be set to false, even if it were true before

Steps to reproduce the behavior

1/ Add a Boolean field to a list

    completed: {
      type: Boolean,
      default: false,
      noedit: false,
      hidden: true
    }

2/ add a pre(‘save’) hook that will set it to true if it’s not:

keystone.list('MyList').schema.pre('save', function(done){
  if(!this.completed){
    console.log('SETTING IT TO TRUE');
    this.completed = true;
  }
  done();
});

Re-saving the document in the admin UI will output 'SETTING IT TO TRUE' every time.

Motivation

This is useful for allowing documents that are constructed over time. I have several lists that allow people to come back and modify the document until a certain condition is met in which case further modification should no longer be allowed.
