Timothy Flynn 69cd0d6599 Ladybird: Update stored URL when a page starts/finishes loading
Similar to https://github.com/SerenityOS/serenity/commit/9782660. Unlike
Serenity's browser, this doesn't affect reloading the page, as Ladybird
refers to the History object for reloading (which is updated already on
page load). However, this URL is used for e.g. crash reporting, so let's
update it here as well.
