A Jasmine spec timed out. Resetting the WebDriver Control Flow - when redirect to new page

I'm beginner in the e2e testing and have a problem. When I do login - I make redirect from login.php to index.php page. But my test is fails with following errors:

..A Jasmine spec timed out. Resetting the WebDriver Control Flow.
F

Failures:
1) Login Page should login and redirect to overview page with CR Operators rights.
  Message:
    Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL.
  Stack:
    Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL.

3 specs, 1 failure

My code:

it('should login and redirect to overview page with CR Operators rights', function(sync) {
    element(by.model('username')).clear().sendKeys('testuser');
    element(by.model('password')).clear().sendKeys('test');
    element(by.css('[type="submit"]')).click();
    expect(browser.getLocationAbsUrl()).toMatch('/overview');
});

So the question is how i can wait when my page will reload and check url?

UPD

I make an Ajax POST request and if login/pass are correct I do redirect to /index.php

UPD 2

I have tried several constructions with browser.wait (browser.driver.wait) but without any success:

it('should login and redirect to overview page with CR Operators rights', function(done) {
    element(by.model('username')).clear().sendKeys('testuser');
    element(by.model('password')).clear().sendKeys('test');
    element(by.css('[type="submit"]')).click();

    setTimeout(function() {
        expect(element(by.css('body')).getText()).toContain('Welcome Test User');
        done();
    }, 1000);
});

and

it('should login and redirect to overview page with CR Operators rights', function(done) {
    element(by.model('username')).clear().sendKeys('testuser');
    element(by.model('password')).clear().sendKeys('test');
    element(by.css('[type="submit"]')).click();

    browser.driver.wait(function() {
            return browser.driver.getCurrentUrl().then(function(url) {
                console.log(url);
                return (/overview/).test(url);
            });
        }, 5000);
    expect(browser.getLocationAbsUrl()).toMatch('/overview');
    done();
});

everything of these don't work :( BUT when I don't use browser or element - it works. E.g.:

it('should login and redirect to overview page with CR Operators rights', function(done) {
    element(by.model('username')).clear().sendKeys('testuser');
    element(by.model('password')).clear().sendKeys('test');
    element(by.css('[type="submit"]')).click();

    setTimeout(function() {
        expect(true).toBe(true);
        done();
    }, 1000);
});

So I guess that here is a problem when use browser and element after redirect.

Any thoughts?

OK, I have resolved this issue by myself, but not sure why element and browser don't work. I have changed

expect(element(by.css('body')).getText()).toContain('Welcome Test User');

to

expect(browser.driver.findElement(by.css('body')).getText()).toContain('Welcome Test User');

So I have changed element to browser.driver.findElement and everything works.

I don't know why it happens, but it works :)

UPD

As I understand, browser.driver.findElement - is not angular way and we should use it if we use non-angular pages. Although I use angular it seems that element and browser doesn't re-initialize.
