Adding tests to package

[freddyaboulton]

Pull Request Description

In order to properly build a conda package, we need to include our test files in the PyPi package by adding init files to the test directories.

After this PR gets merged, I will create release 0.13.0 that pushes these changes to PyPi.

Cool that you figured this out! 😁 👍

@freddyaboulton looks good to me!

One strange question for you: What happens when a dev adds a new test folder? Can we add a unit test or a CI job which checks that all the tests have been added to the evalml package? It would be fine to file this and get to it later. The risk of not doing it is that as we move forward, some tests don't get included in the package and don't run on conda deploy.

Also I checked the dataset sizes and they're super small, so no concerns about adding them to the repo.

@dsherry That's a really good point. I'll file an issue for creating a CI job that checks that each test is added to the package.
