Tests fail because result data is sometimes ordered differently#27

Tests can fail sometimes simply because the values coming from Fauna can be in a different order than the expected ones. This happens mostly at: https://github.com/zvictor/faugra/blob/a2ccb47f293af5f502a464e84423504ff3a263de/tests/specs/build-sdk.js#L193-L197 One easy way to reproduce it is by using [test.only](https://jestjs.io/docs/api#testonlyname-fn-timeout) on that test. That means, replacing ``test(`build an sdk for the 'modularized' example, with standard cache`` by ``test.only(`build an sdk for the 'modularized' example, with standard cache``. It looks like we get one output from Fauna's expanded schema if we run our test in isolation, and a different output if we run it right after other tests. This might be caused by how we are resetting the data in between tests.
