[iOS] - Crash when session is restored on Cr117

[Brandon-T]

Description

• Chromium is restoring every session to WebState and creating internal WebViews which don't apply to Brave-iOS
• This causes a crash because they're expecting the restoration URL to be about:blank but iOS has already restored its webView and the URL can be wikipedia URL. So when we set the URL for History Sync, it will crash as they're different.

Steps to reproduce

1. Open Wikipedia
2. Close the app
3. Re-open the app

• Crash
