"WalletContract required publicKey or address in options" raise for wallets

https://github.com/tonfactory/tonsdk/blame/c560e04ae8f7ae1d81e00353ebbcd2e4256f00aa/tonsdk/contract/wallet/_wallet_contract.py#L23

This line, and specifically `and 'public_keys' not in kwargs` creates an issue where it is not possible to init WalletContract due to "public_keys" only being present for multisig wallets
