Stop bundling tests when packaging

[gaqzi]

Before this the tests would be installed alongside the package, meaning that
there'd be a global tests package installed alongside pyathena.

As a user of pyathena I don't need the tests in production and would rather
not have them installed. :)

I tested this locally and running without this change I saw:
