Subject: [PATCH 1/3] test: add tests for ModelObj.print_line()

Adds missing unit tests for the `print_line()` method of `ModelObj` in `tests/test_structs.py`.
The tests cover cases with no line label and no comment, line label only, comment only, and both line label and comment.
Coverage for `bionetgen/modelapi/structs.py` improved as a result.
