RCTWebViewBridge.m has a classic 'SQL Injection Attack' issue.
The use of "'%@'" - intending to wrap the string in single quotes, will fail if the string itself contains a single quote.
We discovered this when we noted that JSON payloads containing strings with ' characters were not appearing in the WebView as expected.
This PR simply escapes ' characters before formatting into the JavaScript string.
