begin refactoring add_constraints by moving join keys
add_constraints is complicated and difficult to read. This is the beginning of a long process of refactoring this code. First step: moved the join keys out of AssociationScope and into reflection. We then don't need to call `reflection` because now reflection is `self`. `foreign_key` must be named something else because reflection already has a `foreign_key` method and when passed into `JoinKeys` it was getting the wrong assignment. `reflection_foreign_key` seemed to be an appropriate name. I also named `key` `reflection_key` to match `reflection_foreign_key`.
