foreignAutoRefresh does not reuse foreign object instance

[Gytis Jakutonis]

Simple example:

class Book {

    @DatabaseField(foreign = true, foreignAutoRefresh = true)

    var author: Author? = null

}

If I query 10 books of the same author, I get 10 Author instances for each Book. I would expect to get just one instance, shared between all Book instances within same query result.
