We can call gettxoutproof() with a list of transactions. Currently, if the first transaction is unspent (and all other transactions are in the same block), then the call will succeed. If the first transaction has been spent, then the call will fail. The means that the following two calls will return different results: gettxoutproof(unspent_tx1, spent_tx1) gettxoutproof(spent_tx1, unspent_tx1) This commit makes behaviour independent of transaction ordering by looping through all transactions provided and trying to find which block they're in. This commit also increases the test coverage and tests more failure cases for gettxoutproof()
