Reload less aggressively in URI.go
Reload less aggressively in URI.go

Summary:
Firefox (and maybe also other browsers) does ignore-the-cache reload (Ctrl+F5) on `window.location.reload`.
Replace this by assignment to `window.location`.
We can't use `window.location = window.location` because it does nothing if there is a hash.
