CarbonCopySubscriber is not properly invoked on a ticket change event

[Cedric Hurst]

With the CarbonCopySubscriber module activated, 'cedric' listed as owner, and 'steven' listed as cc:

i figured this had something to do with the get_subscription_categories method of the the CarbonCopySubscriber. So I simply mirrored the body of the same method in LegacyTicketSubscriber and the problem was resolved:
