This replaces the ErrDoubleSpend and ErrMissingTx error codes with a single error code named ErrMissingTxOut and updates the relevant errors and expected test results accordingly. Once upon a time, the code relied on a transaction index, so it was able to definitively differentiate between a transaction output that legitimately did not exist and one that had already been spent. However, since the code now uses a pruned utxoset, it is no longer possible to reliably differentiate since once all outputs of a transaction are spent, it is removed from the utxoset completely. Consequently, a missing transaction could be either because the transaction never existed or because it is fully spent.
