Ce 1019 exacttarget update user part3

This is also a bit repetitive to have to be checked in every method. Are these methods going to be called outside the context of these hooks where you'd need to have this safety check? If not, I'd consider moving the check somewhere more general, possibly to where the hooks are registered, by doing something like this to register them:
https://github.com/Wikia/app/blob/dev/extensions/wikia/RestrictSessions/RestrictSessions.setup.php#L30
https://github.com/Wikia/app/blob/dev/extensions/wikia/RestrictSessions/RestrictSessionsHooks.class.php#L16-L22 (which also removes the need for the hook methods to be static and get rid of all the `$thisInstance = new ExactTargetUpdatesHooks();` repetition).
