Possible bug in lib/Sabre/VObject/Parameter.php:

__toString is not allowed to return null, according to PHP documentation, but it calls getValue method which can return null, according to the method documentation.

How to reproduce:

$vcard = new VObject\Component\VCard();
$vcard->add('TEL', '', array('pref' => null));
echo $vcard->TEL['PREF']; // this calls __toString()
