Got a nullref in ChromiumWebBrowser.Load(string url) if bound address changes after dispose was called. Therefor added null checks for managedCefBrowserAdapter.

@DHasi Welcome to CefSharp. Thanks for the contribution! 👍

I'll comment inline where relevant.

I don't believe a null check is required here as browserCreated is never set to false

@DHasi For the sake of getting this PR merged quickly, I think it's preferable to concisely fix the bug your experiencing. As it stands there are a lot of white noise formatting changes that take the focus off the actual proposed fix. There's also a few changes that aren't required in content.

Hopefully my comments aren't off putting. Happy to discuss in further detail if required.

Hi Alex,
thanks a lot for your feedback! This was actually my first open-source-project pull request.so I expected some “mistakes” from my side. :) I will rework my fix and – as you mentioned – focus on the actual problem I found. I’m a very big fan of this project and really looking forward to contribute.
