Bug 1485288 - Fix intermittent browser/base/content/test/urlbar/browser_urlbarStop.js by waiting for URLBarSetURI to be called by using a progress listener. r=mak When the load is stopped, tabbrowser calls URLBarSetURI [1] and then calls onStateChange [2] on its progress listeners. That's the URLBarSetURI call that updates the urlbar value in this case. So to properly wait until the urlbar value has been updated, add our own progress listener in the test.
