fix(service): fix canonicalName generation in JavaAutoTestService #101

- Fixed a bug in the `JavaAutoTestService` where the `canonicalName` was not being generated correctly.
- The `name.replace(".java", "")` was replaced with `virtualFile.nameWithoutExtension` to generate the correct `canonicalName`.
