Owner attribute in instantiate response should be address

[jasny]

Tested it with the potion package, but this probably applies to all packages.

The 'owner' attribute when instantiating the contract is the public key. When getting the information using get_query we get the address.

it('instantiates the smart contract', async () => {
  const result = await contract.instantiate(
    {
      ownable_id: '88pDRu52FpsU3kKHwdvPV21RMkBqVqNnthjfdCesTHQhLnUpanw49n6b2PzGnEy',
      package: 'bafybeie4ts4mbcw4pswzh45bj32ulcyztup2dr7zbbjv3y2ym3q3uuejba',
      network_id: 'T',
    },
    { sender: account.publicKey, funds: [] },
  );

  assert.equal(result.attributes.owner, account.address);
});
