Title: Include on find breaks when irrelevant rows in join table

@sdepold and @mickhansen check this out.

Sascha, the `sync` action creates the cascading constraints so I needed to remove those in this test.

Also, how can I go about setting up cascades in migrations other than just writing the queries?
