AbstractControllerTestCase doesn't respect $this->getRequest()->setMethod()

[superdweebie]

This docs page http://framework.zend.com/manual/2.1/en/modules/zend.test.phpunit.html has this example:

public function testIndexAction()
{
    $this->getRequest()
        ->setMethod('POST')
        ->setPost(new Parameters(array('argument' => 'value')));
    $this->dispatch('/');
}

Which won't work because if a method isn't supplied to dispatch it doesn't look in the request object, it just defaults to get.
