Fix default setting (#740)

* push validate/defaults into datastore

we weren't setting a timestamp in route insert when we needed to create an app
there. that whole thing isn't atomic, but this fixes the timestamp issue.

closes #738

seems like we should do similar with the FireBeforeX stuff too.

* fix tests

* app name validation was buggy, an upper cased letter failed. now it doesn't.
uses unicode now.
* removes duplicate errors for datastore and models validation that were used
interchangably but weren't.
