Issue description

A flash message is displayed at the page load after a redirection and displayed again at the page refresh.

Steps to replicate

Two pages having their own component: page 1/component A, page 2/component B.

Form the page component A, I make a redirect to page 2.

// component A
public function onRun()
{
    trace_log('Component A::onRun');
    return Redirect::to('my-page')->with('message', 'My awesome message');
}

In page 2 / component B :

// component B
public function onRun()
{
    trace_log('Component B::onRun');

    $returnMessage = Session::pull('message');

    if ($returnMessage) {
        Flash::warning($returnMessage);
    }
}

When page 2 is displayed after redirect, the flash message is show.
If page 2 is refreshed a first time (or accessed through a link, or refresh a page in backend your logged in) it show the flash message a second time.
If page 2 is refreshed a new time there is no more flash message.
