Filters wrap in the wrong order

[peterhorne]

<?php

$app->filter(function($route) {
    echo 'Called first';
    return $route();
});

$app->filter(function($route) {
    echo 'Called second';
    return $route();
});


$app->get('/', function() {
    return 'I am the route';
});

Output should be:

Called first
Called second
I am the route

Actual output is:

Called second
Called first
I am the route
