This is a follow up to #1901 and #1882. Depends on #1967.
Essentially before this change, Purchases had both StoreKit1Wrapper? and a PaymentQueueWrapper. The later wasn't actually needed when the first was not-nil, so it was essentially storing (a?, b?). What we really wanted to express is that it could have one OR the other.

This introduces Either to express this requirement in the type system, as well as PaymentQueueWrapperType that will be used to fix #1964.

This is a follow up to #1901 and #1882.

Looks good, just a comment about a possible change but NABD.

These could potentially use the storeKit1Wrapper (and paymentQueueWrapper if we add it) extension functions instead of left and right.

Purchasing: fixed consumable purchases by fixing transaction-finishing (
70365df 
#1965)

Fixes #1964, [TRIAGE-134], [TRIAGE-131], and possibly [TRIAGE-82].

Depends on #1967, #1968.

### Fixes:
- For `SK2` purchases we were never finishing transactions. We are now.
- For `SK1` purchases, transactions were finished _after_ the completion
block was invoked (and tests were very lenient checking that
_eventually_ this happened). This could have lead to race conditions.
- For SK2 only (at least in `SKTestSession`s), this fixes the ability to
purchase multiple consumable purchases.

This is the log from the failing test using SK2:
