In admin UI virtuals can't access field values not included in `defaultColumns`

If you want to include a virtual to your defaultColumns the fields it accesses must be included in defaultColumns as well.

E.g.:

//not working:
Foo.schema.virtual( 'foo' ).get( function(){
  return this.baz;
} );
Foo.defaultColumns = "name, foo";

//works:
Foo.schema.virtual( 'foo' ).get( function(){
  return this.baz;
} );
Foo.defaultColumns = "name, baz, foo";

I assume some filtering of the document happens for speed reasons, which makes sense, but is there some way we can force the document to have specific fields inside our virtual getters?

closing as elemental UI merge makes this irrelevant.
