Add missing def_delegator for constructor_inputs

[beacoding]

constructor_inputs when creating a contract from_file was missing.

We should probably enable passing constructor params with something like this:

    def encode_constructor_params(contract, args)
      types = contract.constructor_inputs.map { |input| input.type }
      Util.bin_to_hex(Eth::Abi.encode(types, args))
    end

as well, and appending it to data in deploy and transact.

Be happy to extend this PR if that's a direction we'd want to go.
