Ensure that WebFramesManager->GetMainWebFrame() always returns a valid WebFrame.

Remove extraneous |removeAllWebFrames| call to ensure a WebFrame exists for the main frame when navigating back then forward on a same page (ex:example.com#link) link.

Additionally, add tests to validate the returned WebFrame object.
