Handling of absence eth_chainId on Web3 provider side

[akolotov]

If a web3 provider used by the wallet does not support eth_chainId call the message Wallet account rejected by user. You need to unlock your wallet. Please refresh the page and click 'Connect' button in your wallet popup appears. It does not clarify the issue.

That's why it is suggested to handle errors appeared when getChainId called and provide more precise explanation what it is necessary to do to address the issue.
