ionic-framework: bug: Controller executing twice - nested states.

Type: <span ionic-type>bug</span>

Platform: <span ionic-platform>all</span>

<span ionic-description>Nested states with parameters and tabs execute the controller twice.

How to reproduce:

The first state manages the tabs

  .state('tabs', {
      url: "/tab/:projectID",
      cache: false,
      templateUrl: "tabs.html",
      controller: "TabsCtrl  as vm",
      resolve: {
        project: function($stateParams, Projects) {
          return Projects.get($stateParams.projectID);
        }
      }
  })

  .state('tabs.tab1', {
      url: "/tab1",
      views: {
          'tabs-tab1': {
              templateUrl: "tab1.html",
              controller: 'Tab1Ctrl as vm'
          }
      }
  })

the seconds loads the specific tabs in the tab list.
