tests(start_directory) Improve checks

what:
- Added monkeypatching to change the current working directory to tmp_path in test cases.
- Simplified assertions for current path checks by removing unnecessary conditional statements.
- Ensured consistency in handling expected paths across test files: test_pane.py, test_server.py, test_session.py, and test_window.py.
