`TestOAuth2ApiService` selected in _production_ build

### Describe the bug

Scenarion:
* Polaris with Eclipselink
* Bootstrapped Polaris
* Starting Polaris
* Running `./polaris principals list`

Yields a runtime exception, HTTP/401 hides the actual cause:

```

Start with the stack trace in TestOAuth2ApiService.java and inspect how the production build selects that service, then trace its use through IcebergRestOAuth2Api.java. Reproduce the issue with Polaris using EclipseLink and `./polaris principals list`; done means the production build no longer selects the test OAuth service and the command avoids this runtime authorization failure.
