Allow for sending a value when deploying a contract

[joaop21]

This is a possible scenario when deploying a contract. We might want to send some funds on a contract instantiation, and a Solidity contract can be payable.
Not allowing a value to be sent on a contract deployment limits the possible actions we can take here.
