tests(legacy_api/test_window): Remove duplicate test_set_and_show_options

why: Test was duplicating functionality already covered in tests/test_window.py
what:
- Remove test_set_and_show_options that tested NEW API in LEGACY test file
- Remove unused OptionScope import
- Same functionality tested in test_set_and_show_window_options (test_window.py:327)
