The configuration can go into the central .simplecov file and then we
just need to `require` simplecov to start the coverage process. This
also avoids duplicating the config if we want to start simplecov from
the rails server to cover the lines used in by the server in feature
specs.

For some reason the order objects were stale here when calling order.update! from either a payment or shipment callback, which was overwriting those states as nil on the order.
The removed test here was checking for adjustments that have an amount of zero and are eligible. If the amount is zero, it will already be marked as ineligible.
The CI build can't find the downloaded file and fails like:
```

No need to slow down the build with partial coverage analysis that won't
be merged in a single report for the whole build.
Also, this makes builds fail because we are not running the whole suite.
