With autodetection enabled, generateTestResourceConfig should look at processed test resources only

[alvarosanchez]

What happens currently, given that resources.autodetection.enabled is set, is the following:

generateResourceConfig

• ✅ Detects resources in target/classes.

[INFO] [INFO] --- native:0.9.28:generateResourceConfig (default-generateResourceConfig) @ package-native-image ---
[INFO] [INFO] Detected resources for /Users/alvaro/Dev/micronaut-projects/micronaut-maven-plugin/target/it/package-native-image/target/classes are [logback.xml, application.yml]
[INFO] [INFO] Resources configuration written into /Users/alvaro/Dev/micronaut-projects/micronaut-maven-plugin/target/it/package-native-image/target/native/generated/generateResourceConfig/resource-config.json

generateTestResourceConfig

• ❌ Detects resources in target/classes. It should be in target/test-classes.
• ❌ Detects resources in src/test/resources. This shouldn't be attempted since a) those are unprocessed; and b) processed test resources will already be in target/test-classes.
