We were making two calls to recurly: one from the SubscriptionController
and another from the SubscriptionViewModelBuilder. This change moves
all the logic to the builder so we only have to do one call.
Squashed commits:

[c7af52d] Overhaul change-plan page, show only plans from current generation
[33d86bf] update plan
[5bbd946] Add a basic plans AB test
This prevents a crash later when we refer to properties
of the plan object, which can end up being `null` when
the `planCode` is either missing, or not a valid code.
