Contract.at actually returns a Promise + missing Deployer.then()

[julienmuller-forge]

Contract.at actually returns a Promise so the type should be
interface Contract extends ContractNew<any[]> {
deployed(): Promise;
at(address: string): Promise;
address: string;
contractName: string;
}

+method Deployer.then() is missing (cf truffle documentation here : https://www.trufflesuite.com/docs/truffle/getting-started/running-migrations#deployer-then-function-)

Could you please publish a fixed version ? Thanks.

Sorry i just noticed there was already a PR for the first one ! Although i think this is not truffle 5 specific, as far as i recall, contract.at() has always returned a Promise
