UnhandledAlertException not being propagated upwards

Issue Description:
When running a Geb/JUnit test using chromedriver (v. 2.42.2, chrome v. 
36.0.1985.125), if an UnhandledAlertException occurs, the client never sees the 
exception.

Partial stack trace:

I have an exception handler in BaseTest that never receives the runtime 
exception:
class BaseTest extends GebReportingTest {
...
    @Rule
    public ExceptionWrapperRule rule = new ExceptionWrapperRule()

    class ExceptionWrapperRule implements MethodRule {
        ....
        public Statement apply(final Statement base, FrameworkMethod method, Object target) {
            return new Statement() {
                public void evaluate() throws Throwable {
                    try {
                        base.evaluate();
                    } catch (org.openqa.selenium.UnhandledAlertException ex) {
                                        ...

Also, in the config, I am trying to handle this Exception there as well:
    chrome {
        def options = new ChromeOptions()
        options.addArguments("test-type")

        DesiredCapabilities dc = DesiredCapabilities.chrome();
        dc.setCapability(CapabilityType.UNEXPECTED_ALERT_BEHAVIOUR, UnexpectedAlertBehaviour.ACCEPT);
        dc.setCapability(ChromeOptions.CAPABILITY, options);

        driver = { new ChromeDriver(dc) }
    }

Neither the exception handler no the config are able to deal with this 
exception.
