utxosAt PAB testing

We implemented this smal contract to test and show what we think is a wrong behavior with the utxoAt function. The function is returning sometimes the complete list of “utxos” for a given address, including the utxos that were already spent.

Ideally this contract is designed to show a strange behavior with the utxosAt function, so we want always to have a single utxo. For that we should change the integer on the validator each time we activate the contract; other way we could endup with more than one utxo for a given address, and that will break the spend and spend-pay actions.
