Uninitialized account error handling

[Kouteki]

Current State

As a user making a maketx call from an uninitialized account, I get the ambiguous account xyz does not exist error

Desired State

As a user making a maketx call from an uninitialized account, I get an error message that sends me to the faucet so I could make a 1st transaction and initialize my account.

Steps to reproduce

• Run a maketx call
• Use an account that never had to or from transactions

AFAIK, the case is not "0 GNOT on the account" - the case for this error is "no in or out transactions happened with this account". This happens because, until the chain knows about the address somehow (ie, its found as a "to" in a tx), it doesn't initialize it (simply doesn't know about some random string of characters gotten from some source of randomness) and you get this error.

Would be great if we could check if this specific case is only when the account is uninitialized, as we can simply change the error message into something more clear.

Thanks for clearing that up @leohhhn

I'll update the description, but I see your PR already is already solving this :)
