lib-storage: fail_mailbox_exists() - Return not found as a success instead of an error

GETMETADATA sometimes responds with “NO [SERVERBUG] BUG: Unknown internal error returned”,
instead of “NO Mailbox doesn't exist”, depending on the actual configuration.
This can happen with the shared namespace.
