Build and tests jobs are not retriggered in case of source code change
Encountered with !123.
Build and tests jobs are not triggered when a push-force, changing the source code, happen. Only the `format` job is retriggered.
This is due to the fact that the extension (`extends`:) is not inheriting but erasing the `only:changes` part:
```yml
.code_changes:
only:
changes:
- silkaj/*.py
- tests/*.py
.changes:
extends: .code_changes
only:
changes:
- .gitlab-ci.yml
- pyproject.toml
- poetry.lock
```
