chore: token registry mint method doesn't throw error when address provided is not a token registry

[justussoh]

The expected behavior is for cli to detect that there's no smart contract at that address.

Input example ? Current output ?

It should be done on more functions than the mint

[justussoh]

Input example:
open-attestation token-registry mint --tokenId 0x89f533e51c8c01f6dacad58f20087fc77e27b39a32caea60039a9355b4aba256 --address 0x67b5Bc373cAA527Cee654d6A0f629ba1E84fAd02 <this address does not have a smart contract> --to 0x87CB17B6d1745389d27c2fdC49560E74E126E2B9 -k <removed private key> -network ropsten

--address flag is for the address of the token registry

Problem:
Does not throw an error when invalid address is input

[Nebulis]

Could you investigate on which more functions this needs to be done ? for instance there is document store issue/revoke too
