Remove parseRequest route equals composition compareator

[nadar]

Remove from luya\web\UrlManager in parseRequest().

// route matches composition exactly, so we have to remove the composition informations
        if ($route === $composition) {
            $parsedRequest[0] = false;
        // now see if the composition (+1 as we add add trailing slash at the end) matches the cutted route request part, if so its composition prefix, remove it.
        } 
     // keep this part
    elseif (substr($route, 0, $length+1) == $composition.'/') { // ...

As the composition will already be removed
