Steven MacLeod af8d509ba9 Bug 1090430 - Make sure a browser is still remote before showing the busy spinner. r=mconley
A browsers remoteness could change between the time we checked it and
when we make the call to show the spinner. We now perform another
remoteness check just before calling _showBusySpinnerRemoteBrowser().
