Why is service undefined in resolve state?

Question

I'm trying to verify that when user try to acces login page, the system redirect to profile if user is logged. To do this I resolve a promise from service that return status user, but the function that return status is undefined. What am I doing wrong?

note 1: at the resolve from last state I try to doing by .then, I don't know if the rest work without .then note 2:extra factories in service doesn't matter

route.js

angular.module('Horarios.routes', ['Roles.constant','Session.service'])

.config(['roles', '$stateProvider', '$urlRouterProvider', function(roles, $stateProvider, $urlRouterProvider) {


$urlRouterProvider.otherwise('/loginr');

$stateProvider
.state('sidenav', {
    url: "/nav",
    templateUrl: 'templates/sidenav.html',
    controller: 'sidenavCtrl',
    controllerAs:'side'
})

.state('loginr', {
    url: "/loginr",
    templateUrl: 'templates/loginr.html',
    controller: 'loginCtrl',
    controllerAs:'login',
    resolve:{
        logeado : function(sessionFactory) {
            return sessionFactory.isLogeado().then(function (response) {
                return response;
            });
        }
    }
})
}])

service

angular.module('Session.service', [])

.factory('sessionFactory',['$q','$http',  function($q,$http) {
self = this;

self.isLogeado = function(){
    var promesa = $q.defer();
    $http.post('scripts/islogeado.php').then(function(respuesta){
        promesa.resolve(respuesta);
    })
    return promesa.promise;
}

self.autentica = function(){
    var promesa = $q.defer();
    var url = "scripts/autentica.php";
    $http.post(url).then(function(respuesta){
        console.log(respuesta.data);
        var usuario = respuesta.data;
        console.log(usuario.nombre);
        var primerNomb = usuario.nombre.indexOf(" ");
        var primerApell = usuario.apellido.indexOf(" ");
        var nombre = (primerNomb>0)? usuario.nombre.substring(0,primerNomb) : nombre = usuario.nombre;
        var apellido = (primerApell>0)? usuario.apellido.substring(0,primerApell) : apellido = usuario.apellido ;
        usuario.nombreApellido = nombre+" "+apellido;
        console.log(primerApell);
        promesa.resolve(usuario);
    }, function(err){
        console.log("error al consultar usuario: "+err.message);
        promesa.reject(usuario);
    })

    return promesa.promise;
}

self.cierraSesion = function(){
    var promesa = $q.defer();
    $http.post('scripts/cerrar.php').then(function(){
        promesa.resolve("cierra");
    })
    return promesa.promise;
}
return self;
}]);

app.js

angular.module('horariosapp', [
    'ui.router',
    'Horarios.routes',
    'Mihorario.controller'
    ])

.run(['$rootScope', '$location', 'roles', function($rootScope, $location, roles){
$rootScope.$on('$stateChangeStart', function (event, next){
    console.log("funcion run");
    console.log(next);
    if(next.resolve.logeado()=='noEntra'){
        $state.go('loginr');
    }else if (next.data !== undefined){
        if (next.data.permisos.indexof(loginFactory.permiso)){
            console.log("is worth");
        }else{
            $state.go('sidenav.perfil');
        }
