Refactor queries

**What it's the actual situation on ARA ?**
This is more a code enhancement (refactoring): a lot of repository classes (XXXRepository.java) use the `@Query` annotation.

**Describe the solution you'd like**
This is not useful and add unnecessary code: it can directly be replaced (annotation to remove) by renaming correctly the method. See https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpa.query-methods

Please note that integration tests are expected to make sure no regression has been introduced.

Locate the XXXRepository.java classes that use @Query and read the linked Spring Data JPA query-method reference first. Review the affected method names, then run the integration tests; done means the repository queries work without regressions after the refactoring.
