@QuarkusTest with quarkus-amazon-lambda-rest does not map REST resources paths and throws 404 for any call.

Describe the bug

Hello,

I use quarkus-amazon-lambda-rest extension and @QuarkusTest for e2e HTTP testing. Mostly because @QuarkusIntegrationTest does not support the aws lambdas. (see this )

After upgrading from Quarkus 3.21.1 to the latest LTE 3.27.1 my tests started failing. But REST endpoints do work in dev/prod modes. The tests worked fine before (even with failsafe plugin instead of surefire, now it fails with both)

Expected behavior

Rest assure tests must find defined endpoints

Actual behavior

Rest assure tests fail with 404.

How to Reproduce?

Use maven, java and below pom.xml

    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

Test

@QuarkusTest
class HealthResourceTest {
    @Inject
    HealthCheckResource health; // injected just to be sure the resource is in the classpath/CDI/etc

    @Test
    void testStub() {
        given()
            .when().get("/svc/health/status") // "svc" is the "root path from `quarkus.http.root-path=${API_ROOT_PATH:/svc}`
            .then()
                .statusCode(200)
                .body(is("OK"));
    }
}

Resource

@Path("/health")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@ApplicationScoped
public class HealthCheckResource implements HealthCheckApi {
    @GET
    @Path("/status")
    @Override
    public String getStatus() {
        return "OK";
    }
}

Additional information

I'm aware about lambda + rest port conflicts (https://github.com/quarkusio/quarkus/issues/33312). It causes really weird no-responses/404/etc. I redirected the event server in my config quarkus.lambda.mock-event-server.test-port=8085. I see in the logs that the resource path and port are correct. (same one i use in dev mode)
