Fix NPE on MultiConversationNotificationState

Use the most recent notification's state to print out log because
mContent is null in case of a notification for multiple messages in at
least 2 different conversations.
And no need sanitizePII() since this log is only for VERBOSE already.

Test: 1) adb shell setprop log.tag.MessagingAppNotif VERBOSE
      2) Receive SMS from different senders
