NullPointerException is thrown when we try to update the result but a session never started

[nadvolod]

This error will be thrown when we try to start a test but a session is never created

java.lang.NullPointerException
	at com.saucelabs.saucebindings.SauceSession.updateResult(SauceSession.java:59)
	at com.saucelabs.saucebindings.SauceSession.stop(SauceSession.java:54)
	at com.saucelabs.saucebindings.SauceSession.stop(SauceSession.java:50)
	at com.saucedemo.SauceConnectTest.teardown(SauceConnectTest.java:39)

This is the test to reproduce it

public class SauceConnectTest {
    protected WebDriver driver;
    private SauceSession session;

    @Test
    public void shouldOpen() {
        SauceOptions options = new SauceOptions();
        // When we start a tunnel, we provide a tunnedIdentifier using the '-i' flag
        // And we can reference that tunnel here
        options.setTunnelIdentifier("NikolaysTunnel");

        session = new SauceSession(options);
        driver = session.start();
        // This is an example of an application that Sauce Labs cannot get to because it's in your internal network
        // In order for Sauce to be able to Securely access your application, we use Sauce Connect
        driver.get("http://localhost:3000");
        assertEquals("React App", driver.getTitle());
    }
    @After
    public void teardown() {
        session.stop(true);
    }
}

The reason this test fails is because no such tunnel identifier exists. Rather than throw a NullReference, we should do a check in our code.
