Improvements in the process of account verification

I saw a strange thing in the process of confirmation twitter account.
If you specify a user name, but do not send a tweet with confirmation, the link to the user will appear in a profile, despite the fact that the confirmation has not been published on Twitter. I think this may confuse some users.
(I have not tested it with other accounts, but I think it will be something similar)

If you then attempt to verify your twitter account through the keybase CLI, you will get a message like below:

> $ keybase prove twitter
> > You already have a proof for gregsonar@twitter; overwrite? [y/N]

It seems to me, then it takes some improvement - not publish a link to the unconfirmed profile at all, or report that the account is added, but not yet confirmed in terminal too.

Start by reproducing the described Twitter account verification flow in the profile and with the keybase CLI command `keybase prove twitter`. Compare the displayed profile link and terminal message before and after confirmation; done means the unconfirmed account is not presented as verified and the CLI state is consistent.
