Async location updates causes flickers

This goes back to #12241 that was fixed with the commit above, but the commit causes flickering in ionic apps. I will note that @IgorMinar's patch does not cause any flickers.

Steps to replicate

1. Create an ionic project and add ios

ionic start myApp tabs
cd myApp
ionic platform add ios

2. Update the local version of ionic.bundle.js in www/lib/ionic/js/ with this build of ionic and angular 1.4.7

Then deploy to an ios simulator running iOS9.

You should see flickers as you change tabs.

Given that iOS 9.1 has been out for a while now and take up of that must be at least as high as the 9.0 roll out - is this really an issue any more?
