A common mistake for beginners is to attach a controller in both the
$routeProvider and also in the html document using the ng-controller
directive. This change highlights this, to help prevent developers from
doing so in the future.

fix($compile): instantiate controlers when re-entering compilation

When we re-enter compilation either due to async directive templates or element transclude directive
we need to keep track of controllers to instantiate during linking.

This piece of info was missing when re-entering compilation and that's what this commit fixes.

I also reordered the properties in the previousCompileContext object.
