ducky/subscriptions/client/subscription.go

Update subscription_creator to use the new strategy. When creating subscriptions through the client, detect when the returned error is saying the account already has a subscription, or the subscription already exists in stripe. Add an UpdateSubscription function that will update a subscription through the API. Update our subscription_creator listener to listen for profile creation and login verification messages. This mainly involved fixing the constants (the system, model, and topic) that the listener for profile creation was listening for. It also meant adding a new updateMessageHandler that listens for login verification, tries to create a subscription that has the user ID and email of the login that was verified, and if a subscription already exists, updates it instead to use the email address that was just verified. This will ensure that users get their receipts automatically emailed to them by Stripe.
