[in_app_purchase_storekit] Fixes manual invocation of `finishTransaction()` triggering fatal crash (#8071)

Fixes https://github.com/flutter/flutter/issues/154763

From the Apple docs: 
https://developer.apple.com/documentation/storekit/skpaymentqueue/1506003-finishtransaction
`If you call finishTransaction(_:) on a transaction that is in the [SKPaymentTransactionState.purchasing](https://developer.apple.com/documentation/storekit/skpaymenttransactionstate/purchasing) state, StoreKit raises an exception.`

For some reason even though the old Obj-C implementation didn't have this check, it didn't crash. This adds an explicit check for the purchasing state.
