Update web_profiler toolbar when in sandbox mode

This will update the web_profiler toolbar with the data from the sandbox request. I am currently running with this patch in dev, but you may want to consider this a WiP as I imagine this is something you would likely want to be configurable at the bundle level. Thoughts?
