Title: Patch for potential crash caused by inserting null string into NSMutableArray

ABMultivalueCopyLabelAtIndex may return null. Null values cannot be
added to an NSMutableArray. This patch checks for null values and inserts an empty string instead and avoids a crash. The string could be any label you choose, such as "Other".
