Ce 1018 exacttarget refactoring i2

But, [this](https://github.com/Wikia/app/blob/bf0ceefa16/extensions/wikia/ExactTargetUpdates/tasks/ExactTargetUserTaskHelper.php#L173-L176) is now exactly the same as [this](https://github.com/Wikia/app/blob/bf0ceefa16/extensions/wikia/ExactTargetUpdates/tasks/ExactTargetUserTaskHelper.php#L178-L181) so the check serves no purpose. Was the change to the parameters a mistake then?
