Transfer Events Not called when transferring from anonymous user id

Scenario:

1. User installs application
2. User makes a purchase
3. User creates an account, logs in, and then calls identify on RevenueCat
4. User restores purchases to transfer purchases to newly created account

Expect Series of Webhook Events

1. INITIAL_PURCHASE event is sent to webhook upon completing step 2.
2. TRANSFER event is sent to webhook upon completing step 4.

Actual Series of Webhook Events

1. INITIAL_PURCHASE event is sent to webhook upon completing step 2.

Use Case: 

Given that a user can make a subscription before creating an account, we rely on the RevenueCat webhook to give us a Transfer event when a user restores purchases after creating their account. This allows us to use our server to update the user in our database with the current product they are subscribed to.
