ui-sref does not set href when url is empty string

[emilbayes]

Example JS:

$stateProvider
      .state('frontpage', {
         url: '^',
         templateUrl: '/js/templates/frontpage.html'
      })
      .state('news', {
         url: '/news',
         templateUrl: '/js/templates/news.html'
      })

Example HTML:

<a ui-sref="frontpage">Frontpage</a>
<a ui-sref="news">News</a>

Rendered HTML:

<a ui-sref="frontpage">Frontpage</a>
<a ui-sref="news" href="/news">News</a>

The first <a> is missing the href="" attribute, however the click event is bound, so this should be an easy fix. I'd be happy to submit a PR, but there seems to be a long lead time on reviews/merges.

What happens when url: ''?

Same as above, no href
