isConnected - probably more of a question

[juliancwirko]

Does it make sense to check the account address in isConnect instead of returning the isInitialized?

isConnected(): Promise<boolean> {
  return new Promise((resolve, _) => resolve(this.isInitialized()));
}

I think this isn't concise for all providers. For example, in the extension, it checks the account, it probably should check the address: https://github.com/ElrondNetwork/elrond-sdk-erdjs-extension-provider/pull/6, but maybe I don't understand how it should work.
