Title: Add toString for Expression

When creating through the relationship synax ->foo()->create() an Expression passed in the array was giving the following Exception: http://pastie.org/private/g8cvwvgjgfmjxjkv8ttlyg

Setting this toString has fixed it, and seems like a fairly logical thing for it to do anyway.
