reflectionexception handling isn't needed anymore

[x-yuri]

zombor said that :) Here it is. One can use HTTP_Exception_404 instead

moreover, I discovered that Request::$current might be NULL while handling exception (ReflectionException in this case). And yes, it was set right before this line, but it is NULL in exception handler (I forgot to add static keyword to method). It seems, php decided I don't need Request::$current anymore
