refactor(iterm2): simplify init save call and clean up string quoting

- collapse conditional save_window_id call into single unconditional call
- fix applescript string quoting to use consistent single-quoted style
- collapse multi-line escaped_session_id assignment to one line
- update test assertion to match new save_window_id signature
