Subject: [PATCH] Fix sharing and around three errors related to Undefined
 array key "CLOUD"

We try to access $contact['CLOUD'] when it might not be set. As a consequence of that 3 PHP errors are generated the last one being an uncaught exception that makes it impossible to share files locally.

This patch adds a simple check to ensure the value exists before using it.
