[Owncloud] vcard::addFromDAVData() fix [patch]

[oc.guillaume at zitta.fr]

Hi,

$data is a vcard string
which is converted to an object => $card
and self::add is called with $data

This patch correct that and add a check at function argument level (like 
in edit function).

I don't know if ML is the correct media to purpose patches...

Regards,

Guillaume ZITTA
