Title: Add warning when load request, but not data given

This can cause some really weird things to happen. For example, if you do a post and the sever simply returns `{}` or `{"model": null}` this will keep records dirty forever. In general this can really just mess stuff up. I made it a warning because it's not exactly a problem, but an unexpected case. I can make it an assertion if needed.
