Add socket repl eval code escaping

Fixes different escaping behavior for socket repl connection and others. Steps to reproduce the issue: 1. Create a `ClojureSublimedEvalCode` hotkey with `"` in the code: ``` {"keys": ["ctrl+h"], "command": "clojure_sublimed_eval_code", "args": {"code": "\"Hello!\""}} ``` 2. Connect to a raw nREPL and press `ctrl+h`. You'll see `✅ "Hello!"` in the status line 3. Connect to a socket REPL and press `ctrl+h`. You'll see `⏳ "Hello!"` in the status line Another way to reproduce the issue: 1. Create a `ClojureSublimedEvalCode` hotkey with `"` in the code: ``` {"keys": ["ctrl+h"], "command": "clojure_sublimed_eval_code", "args": {"code": "(str \"Hello!\")"}} ``` 2. Connect to a raw nREPL and press `ctrl+h`. You'll see `✅ "Hello!"` in the status line 3. Connect to a socket REPL and press `ctrl+h`. You'll see `❌ RuntimeException: EOF while reading` in the status line This PR fixes the issue in both cases
