What does this PR do

When com.google.android.webview is not found by the OS, Fatal Exception: android.util.AndroidRuntimeException: android.webkit.WebViewFactory$MissingWebViewPackageException: Failed to load WebView provider: No WebView installed is throw crashing the app.

This PR prevents @react-native-cookies/cookies from throwing such exception, preventing the app from crashing

How to reproduce the crash

  1. Be on a physical device
  2. Open the Settings app and then navigate to All apps > Search for WebView > Disable

How does the PR work

This PR postpone accessing the CookieManager instance (which could throw MissingWebViewPackageException) until when it's necessary, instead of doing when the native module is initialized.

private CookieSyncManager mCookieSyncManager;

CookieManagerModule(ReactApplicationContext context) {
super(context);
this.mCookieSyncManager = CookieSyncManager.createInstance(context);
this.mCookieManager = CookieManager.getInstance();

Lazy get CookieManager instance - basically try to only crash when actually using the library

cookieManager.setAcceptCookie(true);
return cookieManager;
} catch (Exception e) {
throw new Exception(e);
