Applying `includes` and `joins` to a relation that selected additional
database fields would cause those additional fields not to be included
in the results even though they were queried from the database:
posts = Post.select('1 as other').includes(:tbl).joins(:tbl)
posts.to_sql.include?('1 as other') #=> true
posts.first.attributes.include?('other') #=> false
This commit includes these additionally selected fields in the
instantiated results.
