Uptick to ecto 2.2, and looking at fixing up the tests

[aforward]

I have upgraded to ecto 2.2, and wanted to bring this library along for the ride.

The tests were not running locally out of the box for me, so I made a few additional changes to help get them back on track.

I took insight from Question #133, as well as added a ecto_repos to the config.

Finally, I added () to timestamps to remove a warning.
