Callback should be called by call_user_func

[Chitoku]

Core::handle calls $callback directly but this is inconvenient in following case when using in PHP < 5.4.

<?php
use mpyw\Exceper\Convert;

class Foo
{
    public function that() {}

    public function bar()
    {
        Convert::toErrorException(array($this, 'that'));
    }
}

I actually encountered this situation in my ancient environment, which does not allow use of $this inside closure.
