Title: Minor cleanup in OC_OCSClient::getKnownledgebaseEntries. Fix for #487

Problem originates in OC_Template::assign. It transforms NULL into empty string.
https://github.com/owncloud/core/issues/487#issuecomment-10933619

There is no need in printing entries from anything but array anyway.
OC_OCSClient::getKnownledgebaseEntries is cleaned for better readability and to comply with style rules.
