"Please put it in your wallet." is too demanding

Here's my current conversation with keybase during the paper key setup process:

```
Have you written down the above paper key? [y/N] y
Excellent! Is it in your wallet? [y/N] n

Please put it in your wallet.

Now is it in your wallet? [y/N] n

Please put it in your wallet.

Now is it in your wallet? [y/N] n

Please put it in your wallet.

Now is it in your wallet? [y/N]
```

I think what you mean, at least after the first go round, is that you want me to put the paper key in a safe place, and that if I want to provision new devices on the go, it's useful to have it in a container that I often carry with me. I don't want to keep this bit of paper in my wallet, though I will put in a safe, memorable place. I don't like lying to my security software during this kind of conversation, so I'd like it if keybase could just help me make a good decision that works for me rather than demanding a particular action. (Also, some people use purses, bags or pocketbooks, rather than wallets.)

Start by locating the paper-key setup prompt in the Keybase client and review the flow shown in the issue. Update the interaction to avoid requiring a wallet specifically and verify that the revised prompts support storing the paper key in another safe, memorable place.
