Move unit tests into source

Move the unit tests into the relevant source files. There's no need for them to
be seprate, especially when the `tests` directory is meant to be for integration
tests.

The deserialization tests that include JSON files are still in the `tests` dir,
along with the public prelude re-export tests.
