quarkus: Kotlin no-arg/jpa compiler plugin ignored when recompiling in continuous testing mode

Describe the bug

In a Kotlin project that uses the no-arg / jpa Kotlin compiler plugin, entities cannot be changed in continuous testing mode because the compiler plugin is not used when the affected entity class is recompiled on demand. As a result, tests the fail due to a missing no-arguments constructor.

Expected behavior

Entites can be changed just as any other code and tests simply continue to work.

Actual behavior

How to Reproduce?

https://github.com/languitar/kotlin-panache-reload-issue contains a project to start with

1. mvn quarkus:dev
2. Start continuous testing by pressing r - tests will execute successfully
3. in TestEntity.kt uncomment the line containing uncommentToTriggerBug and save the file

Tests will re-execute and fail.
