Over reliance on end to end tests

[loganripplinger]

Currently in the Data Resource API we have an over reliance on end-to-end tests.

In order to test a lot of the functionality at the interface level it requires that we spin up the database and build the ORM models.

I'd like to see more unit tests interacting with SQLAlchemy and the routing. In order to do that we need to create some new testing patterns.
