This PR fix a few things: 1. The SQL Lab redirect was not working correctly, since changes to the form controls were not being picked up. Instead, the auto-populated query corresponded to the **saved** chart, not the one being visualized. 2. The redirect code was using the [URL interface](https://developer.mozilla.org/en-US/docs/Web/API/URL) without a polyfill. I changed the code to use `uri.js`, which is a dependency. 3. The error message was using the `notify` code that was removed. I changed it to use the chart alerting instead.
