$urlRouterProvider's when function has redirection problems

[nmrm]

$urlRouterProvider has a problem if the incoming path that I want to redirect is empty and there is a state with an url that is also empty.

If I declare something like:

    $urlRouterProvider
        .when('','/staff')
        .otherwise("/error");

and then I declare a named state with an empty "url"...

When calling the webapp in it's root format, http://host:port/webapp

1. Chrome, ignores the $urlRouterProvider and jumps into the state with the empty url (bug).
2. IE and Firefox works fine following the rule in the $urlRouterProvider, jumping into the state that has the '/staff' associated url.

The 1) glitch started happening since lib version 0.2.16 and only in Chrome browsers.

Hi, I'm facing the same problem with Chrome. Plunkr here: https://plnkr.co/edit/FrDapa80tndHvyGW6ckt (minimalistic example)

I've set
$urlRouterProvider.when('/main2', '/main2/sub1/subsub1');
$urlRouterProvider.when('/main3', '/main3/sub1/subsub1');.
So clicking on the link "Main 2", it should open automatically its subsub1 view. The same with "Main 3".

When I use version 0.2.16 and 0.2.17 of ui-router it's not redirecting to /main2/sub1/subsub1" in Chrome, but in Firefox and Internet Explorer it does. The automatically redirection to "/main3/sub1/subsub1" works in all three browsers. With ui-router 0.2.15 everything works as expected.

We suspect this may be related to merging in #1585 and the sort order of routes changing. We plan to revert #1585 and targeting this to be back to normal in 0.2.18.

Sorry for the troubles.

@christopherthielen, @Spessi, @nmrm: I submitted a PR that likely will fix your issue with Chrome.. #2502

Basically it just ensures a stable sort on Chrome for the sorting that got added in #1585.

I'm also open for reverting the PR that added the sort - but we may be able to keep that sort and not have Chrome issues with my PR.
