Log to detect usage of whitelistToken when sending non-PI target

Log ActivityManagerService.sendIntentSender if the target is not a
PendingIntent and a non-null whitelistToken is sent to the client.
This is simply to detect if there are real cases this would happen
before we decide simply remove whitelistToken in that case.
